Mount St Helens is Fuming!

The last eruption of a volcano on the continental US was Mount St Helens in the 80s. It was mostly steam powered, and made apparently some spectacular lightning. It also blew down a load of the trees to the north, which I didn't really get to see on this trip.
If you do get down to St Helens, I recommend the Forest Learning Center, I found that pretty fun! Shame about the wind though, I would have loved to have flown the planes here.

Like a kid in a candy-made-of-science store!

Mate: I doubt you'd have been "safe" on the south side of St Helens when it blew. The 18 May 1980 blast decapitated about 300+ meters of the volcano's summit; it beheaded glaciers which melted producing great mudflows down the south-side drainages. If you'd have been on the south side of MSH 18 May 1980, you'd have been in serious shit.

if you cool ice cream quickly the crystals are quite small and makes for a much smoother texture, where as if it takes a longer time to cool the ice cream the crystals are much larger in comparison. just like the volcanic rock.

Heartwood is the xylem that no longer transports water. It is for its central location. It functions in support for the tree. In very old trees, it can be rotted away, while the tree itself still lives.

Sapwood is so named because it transports sap, meaning water and minerals in this case, from the roots to the leaves. This functional xylem is made out of the same cells, tracheids and vessel elements (not the latter in conifers) as heartwood, only it actually transports water.

Pith is not the same as heartwood.

Stem (trunk) anatomy radiating outward from pith (center):

Pith (spongy parenchyma tissue), primary xylem, secondary xylem, vascular cambium (actively dividing layer that produces secondary xylem and phloem), secondary phloem, primary phloem, cork cambium, and cork.

Heartwood is xylem that has stopped transporting water. This consists of all primary xylem and much of secondary xylem. The division between heart and sapwood is only due to water transport.
