Next we stop at a favourite: Saskatchewan Crossing. #strataday. Loess, paleosols, and three (!) volcanic ash: Mazama, Mount St Helens Yn and Bridge River. Doesn’t get much better, unless you like glaciers. We finish at Athabasca Glacier. Beautiful but heart breaking in her steady retreat. 🧪⚒️
TA Shaun, from VARG, in his element teaching the students about volcanic ash, you can see two clear in this picture, Mazama at his knee and he is looking at Mount St Helens Yn A group of young Bighorn sheep by Athabasca Glacier - a classic site in the Rockies!  Student Lachlan looks to the distance inspecting end moraines with the Athabasca glacier behind him. Saskatchewan River Crossing with the loess cap on the terrace to the right, full of silt, paleosols and tephra!
