 Hello, thank you for joining me, just arrived in the larder in the Buckinghamshire village of Iverheath. We're going to do part two of the rather secretive river Alderbourne today. Part one, we followed the river from the edges of George Cross down through Fulmer, through the water splash and we finished not too far from Iverheath. Well, today we're going to see what else we can find of the river and follow the rest of its course and just see where it takes us really. As I said in the first part, it's a rather secretive river. There's not many places you can actually see it, so it's a bit of a challenge to actually find the river in the first place but we're going to do that. We're going to have a look at a couple of the streams that join the river and just see what we can see really. I have got wellies on so I might get in the river. I'm not necessary thing of trying to go through culverts like we did in the first one. Like I said in the first one, if you watch it, have a look at Lincoln Street now. You'll see what I mean with the first one. It was rather difficult to get through certain parts of the river. That's either Iverheath or his centre, by the way. Just going down this little dead-in road because there should be an alleyway down here. I know the alleyway runs on the back of those houses but there should be another alleyway. Whether it's here, it'll take us to the stream so somewhere beneath this estate there's a stream in a culvert. So yeah, if we go up here what we should effectively be able to do is find the stream that flows into the river Alderborne and then we'll follow that down. We're going to see a bit more of the M25 again like we did in the last video. Just see where the Alderborne takes us really. So right yeah, let's go down here. I think I can already see something of a stream so it's going to be a bit fun like part one was down here. Been down here for quite a while. So I remember coming down here once as a child and seeing a stream looked on the map and worked out and joined the river Alderborne. So this is our first sighting, this bridge here. So adding to the secretness of the river, no idea what obviously goes through someone's garden. As I said it must have been culverted through the estates. The estates around there known as Pinewood Green, I couldn't see anything of the river there. So our first sighting of this stream is, there you go, flows under the bridge. Looks like there's, here too. Well let's go here. So this is out here, this is known as Iverheath Fields. Iverheath was built on the Heathland, there's the village of Iver, not far away. So then later came Iverheath and this is what's left of the Heathlands or more rather out there is. And you can probably already hear, I can certainly hear the sounds of DM-25. So there's the stream. What I'm going to do is I'm going to follow this stream through the woods. It will cross the main road and then I'm going to find another footpath. We should see this stream one more time before we find the actual main course of river Alderborne. I went back over the bridge and still in the woods. I've just come down to here and I said my next sighting of the river was pretty near DM-25 but I just thought for this stream that doesn't really have a name that joins the Alderborne. This was a really rather attractive little section of the river and I thought it's a shame not to feature it. So the bridge where I was a moment ago was just up there to the other side of these bushes. So what we'll do is we'll follow this little section of the river down here and towards the road and then I'll either go back on myself. I've had a look at the map, I've worked out where the footpaths go and find my way around. Now if you're probably watching this video you can see the sun's out, looks like a really nice spring day. Just so you know when I was driving here literally 10 minutes ago it was snowing. The other side of either heath it was snowing. So it's one of those sort of days today so who knows what else we're going to encounter on today's video other than looking for rivers. So I'm going to continue down there and see where this little stream takes us. I'm now walking down the footpath which runs from the Denham Road to the Slough Road. So the Denham Road and the Slough Road both leave either heath and go to Denham and Slough respectively. This footpath runs by beside the M25. Now as for that stream which we found in either heath we should find it up here and it's got to be at the bottom of this little hill here. It'll go under the M25 through a culvert. I'm not going to attempt to get in it or go through it today. We might later on but I'll see but at the moment if I'm doing any going in the rivers it'll be later on. So what we've got here. Right well the ground here looks like it has been waterlogged so obviously does flood here sometimes and here we are here. Here is the stream. So the stream with no name which we saw up at either heath is just here. It goes under this track and into a culvert. So that will take it under the motorway. It will go down there towards Southlands Manor. Now Southlands Manor I've been told is a very attractive country house but it's all private so we can't see that. There is a footpath that runs past Southlands Manor but it's on the wrong side to Cedar River Alderbourne. So I thought that would add what it's going to be for me quite a long walk today. It was probably we're looking at adding at least a couple of miles to go down there so and we probably wouldn't see the river so that's why I'm not going down there. So I'm going to now continue on up here to Slough Road and we might eventually actually find a river Alderbourne that this video is supposed to be about. I've reached the summit of my walk so this is as far away from any waters we can possibly get but that stream we're following basically ran along the bottom of that valley there. Iverheave's over there. The reason I thought we'll just record this little bit is well one thing I mentioned the Slough Road. That is true but the Slough Road actually goes to Uxbridge. So anyone who looked at the map was like of course yeah it goes to Uxbridge because of course it would have been the road from Uxbridge to Slough and pass through Iverheave. So if you look out there the skyline over there that's Uxbridge. I can actually see the building on the site of Uxbridge Vine Street Station. If you want to know about that have a look at the link on screen now that's my Lost Railway Stations of Uxbridge video and I can see right across to Uxbridge Common over there somewhere's Denham. Now the camera's not picking it out but I can just see Wembley Arch in a distance. What I'm going to do I'm going to continue over this way and make my way round to the Slough Road which goes from Iverheave to Uxbridge and then we like I keep saying we might actually try and find the river Alderbourne. Let's just have one last view look at the view over to Uxbridge. I've come to the end of that footpath so I'm now on the Slough Road which as I said goes towards Uxbridge. So Slough Iverheave is that way looking ahead you can just see the skyline of Uxbridge in the background. We're leaving Iverheave now there's the sign Iverheave please drive carefully. So goodbye Iverheave now Slough Road we're going to go down here now this this is a public footpath sign obviously says poke bridle actually but we can walk along here to me this looks like an old road so I reckon what happened was when before the motorway this was the Slough Road when the motorway was built they put the road on a new alignment to make it so behind us it's across the motorway so what we're effectively doing now is we're doing I know I do old railway walks I don't often do disused road walks but here we are we are walking along a disused road not quite as exciting I don't think it's an old railway but still you know a bit of fun I'm hoping though when we get to bottom down here we might actually find the River Audubon so see what I find. I've just come further down this disused road or Slough Road old course whatever you like to call it see how the pavement's still there I don't think a car or any kind of vehicle has been down here for a while but what we finally come to well the motorway second but this bridge is the River Audubon you can see the disused road ends rather abruptly so that's why we're about to build that newer alignment up there to take the road well over the Audubon first but the main object was over the motorway so this bridge here looking downstream there's definitely a river there but you can't see a great deal because there's other trees with ivy on them but if we look upstream we finally get a better view of the Audubon for the first time today what we'll do we'll go down we'll leave this old bridge we'll go down have a look at it and we'll have a look at the river so motorway there the foot path which this road has become goes on down there parallel to most way which I will go down we're not finished recording this clip so into these little glades here and see what we can see well firstly we have a rather impressive large culvert you can just see to the other end I did just before making this clip grow up there I couldn't see a lot on the other side but what happens immediately on the other side the river kinks and it goes under the motorway so there's like another culvert literally around there it's all private land but there is one other place I'm hoping to show you the Audubon upstream of here but in order to get to upstream we've got to follow the foot path downstream I'm not going to go in the river the reason this this stick there is in the river that because before I record this clip I came down and tested it and as we found before it's very silty so I'm not going to go in there's your old road bridge for you so I'm going to follow the foot path on downstream oh one other thing I did want to point out see there you can just see the remains of what must have been roadside utilities coming across here no doubt they've been diverted and they're up there somewhere interesting to compare though the old and new bridges so here it is purely a bridge just to take the river out the road over river rather whilst here it's more a full-on tunnel the roads up higher on an embankment and obviously rivers naturally wouldn't go through this sort of tunnel so yeah difference in between old and new road buildings anyway I'll leave you with one last look at this culvert and then I'm going to continue downstream and see what else we can find well as you can probably hear I'm continuing to walk along beside the M25 the older born is somewhere in there it's a private estate um can't really see anything but up here somewhere is the Colmbrook and the confluence of the Colmbrook but there's supposedly a public footpath under the motorway um alongside the Colmbrook which will take us upstream and hopefully find it's complicated I know this video and show us where the river Colm goes so well here we are look this is the Colmbrook and right okay this is strange as for the footpath under the bridge I've seen low bridges in my life but this is this is low look at this this is footpath to Uxbridge this is the most ridiculous looking footpath I have ever seen I'm actually having to crawl along this this is a this is a public footpath I can just about there crouch and walk I think what I'm going to do I'm going to go right through because this is too fun not to um when I get back up this footpath eventually we'll go to the Uxbridge Road sorry the Slough Road I'm then going to come back along the Slough Road and uh we'll come to there again and then we'll find what we can find further up the Colmbrook but have a look at that for a view in what must be the lowest public bridge I've ever ever been under okay so I think we need some lights this has got to be the weirdest place ever before one of my videos um I must be halfway between the M25 um well I mean sorry halfway in the middle of two carriageway so I can't just stand up here we're looking that way that's the river and this is the girder between the two so there's a little section where I can stand up I'm gonna have to get back down and uh can see daylight continue down this um as I keep saying the weirdest weirdest public footpath I've ever ever been down in my life I'm gonna just get back down my hands and knees and carry on crawling I think goodbye strangest public footpath I've ever been down and and what happens up here it's a public footpath carry on see what we find we was up there a moment ago that's the Uxbridge and Slough Road so the Aldervorn flows along the other side and somewhere over there which we have to go back to it joins the Colmbrook here but we're now going to follow the footpath and try and find the Aldervorn upstream I've since walking under that ridiculously low bridge under the M35 I have been following this very windy footpath um beside the bank of the Colmbrook so the Colmbrook is a river that comes off the river Colm and later rejoins the river Colm maybe one day we'll do a river do a video on the Colmbrook but um and the Colmbrook does really seem to be stealing the show because it's river uh this video supposedly about the Aldervorn but seems to the Colmbrook has taken over anyway here this is the Colmbrook so the reason we're walking upstream of the Colmbrook is to try and find somewhere downstream of the Aldervorn confusing I know so this is that um footpath side so I suppose this footpath before the M25 was built was pretty just a rather easy footpath to walk along the M25 is what's complicated things talking of more going low for some reason that's there um I don't know why we're about to go into London here's the London Borough of Hillingdon so the Colmbrook is the boundary between Buckinshire and London and Greater London in this case London Borough of Hillingdon anyway I'll see look it is called the Slough Road Slough's that way actually it's that way it's just always confusing you're in either heath and you talk about if you're in either heath and you're giving someone directions to go to Slough I mean to go to Oxford you tell them to go down the Slough Road it's confusing anyway this is the Colmbrook um so what I'm going to do now I'm not going to go any further into London we'll do some videos in London in the future I've got to go this way because there's a weird looking dead-end footpath on a map um and I'm hoping not promising hoping we might find something more of the river Aldervorn if we don't know um I'm probably going to continue walking up here and I'm going to end up back at where we found that low bridge so I don't have to go under it again and um we'll see if we can actually find the confluence of the Aldervorn and Colmbrook if we can't um because that's what happened with the Mizzborn we never actually found the confluence of the Mizzborn and the Colm um we'll worry about it when we get there but we'll we don't finish with the Aldervorn and finish with the Colmbrook but right now about here somewhere underneath these pylons there should be a footpath so I'm going to go and find that we'll just come down this little lane from the Slough Road and it's dead end it's shown on the map as a public footpath but again dead end so there was literally nothing else I could do other than come back um the only clue is there's a farm shown on the map as Watergate Farm so um there's clues to water so the Colmbrook must be somewhere behind these houses the Aldervorn as I said it comes as a giant S over there and then it would go so the only other public place you could really see it is where we saw it at the Colvert under the Slough Road so it goes under the motorway we can't see that one there's the Colvert under the Slough Road it then we're yet to find where it joins the Colmbrook I'm guessing it might be on public land as the confluence with the Mizzborn and the Colm was um but what we'll do we'll definitely go back to that low bridge we'll follow that footpath and we'll just just see what we can see really so it's a bit of a strange video today but um that's what happens when you go and try and follow secretive rivers um they don't want to reveal their secrets well I've now come full circle I've been over the M25 we're walking down the same footpath again towards the um what I'm thinking has to be the lowest ever bridge on a public footpath um what I'm gonna do I'm gonna show it to you again I'm not going through it again this time so M25 is behind that fence that's river Colmbrook look at it it's so low look the the roof of it's barely higher than my knees it's this this has to be the lowest bridge on any public right away if you know a lower bridge on a public right away please comment now and within reason I might just go there and make a video but I would be very surprised if there's any lower bridges on a public right way than that anyway from not going under a low bridge let's go over the Colmbrook now as for the confluence as I've said with the Alderborne I have a feeling it's somewhere in there in that private state so we may not see it we just glimpse you can't really see much I can just see water through there I reckon it must join there I'll confirm that later on so we might not actually end this video we didn't start by the Alderborne we might not end by the Alderborne if we can't end by the Alderborne we'll end by the Colmbrook but um another view of that low bridge and a falling leafing willow I'm going to follow the footpath now along by the motorway see what we actually do find well here I am I'm now standing in the middle of the Colmbrook um as for the confluence of the Alderborne and the Colmbrook it was literally right under our noses just the other side of that bridge where that fence was the Alderborne joined there I realized that from a map but I couldn't have shown it to you because it was on private land so I've continued to walk along beside the motorway and the Colmbrook and I said here I am in the Colmbrook the Colmbrook continues that way and eventually goes into the River Thames we're not that's a walk for another day one day I will do the Thames I know I say that I do mean it one day I'm going to do the Thames I'm going to continue to follow the footpath and do a circuit go back to Iverheath find my larder and go home and have a couple of teas so I hope you enjoyed this video of not so much of the River Alderborne um the River Colmbrook the lowest bridge ever that I've ever seen thank you very much for watching please do feel free to like subscribe and comment and from in the Colmbrook goodbye
