The elliptical trench was 11 metres wide and 80 metres long. The side trenches were 1 metre wide but we had to widen it to 9 metres at the rear and 5 metres at the front for the trench to appear as circular as possible from the cliff viewpoint.
@zcarenow One, depending on costal conditions the tide can move *much* faster than a man walks. Two, the tidal creeks fill up *first* - what was crossed with one step on the way out suddenly has become a 50-foot river moving much more swiftly than even Mark Spitz could swim. Three, while the tide moves *in*, the tidal creeks can have undercurrents still going *out* (not as seldom as you might think). Four, what was solid, almost dry sand quickly becomes mud in which you sink in.
@zcarenow Walking the mudflats is fun, and educational, but it is a calculated risk. Those who know the risks are not in danger, only those who "don't get it" and think that they "just need to back inward" are the ones who don't do so in time and get caught by the tide.
Is that about 1.2 km/hr?

We dug the trench between the low and high tides.
