nice trip.. the snow looks heavy.. do you think the ice is still ok?.. i wonder when it's covered with spring wet snow..
the drifts in the trees at the outlet of the Loch are huge ..
The snow was heavy with a pretty thick crust that was nearly frozen enough to support us in the sunny spots. Only the very windy spots were blown clean down to the consolidated snow where we were able to cruise.
I think the ice is still fine other than around rocks in shallow water. I shoved my pole down into the snow where we were crossing (the north end where all the snow collects) and it was 45 inches deep. The last foot was water. The weight of the snow pushes the ice down and water comes up through the cracks.
Generally, the ice itself turns into those vertical crystals and the ice breaks up by falling apart (like calving on a glacier) but the crystals are locked together. I've walked on this type of ice when it feels a bit spongy (not recommended) but I wouldn't doubt if it'll be another week or more before it is like that. Snow on the ice seems to slow down the breakup.
I've never seen the drifts at the Loch's outlet this big, the big main drift that you go up to get level with the Loch is WAY huge. I wouldn't doubt if at it's deepest point it is 50 ft. deep. It is built way out beyond where it normally ends. From there, it is one long flat drift right out onto the lake.
The rock outcropping below the tarn only has 10 ft. cliffs below it. You could just about down climb the knob and jump off onto the snow below. I think those cliffs are at least 80 ft. tall in summer.
Here's a picture from June 21st of 08:
The shorter rock cliffs on the right side of the knob are nearly buried and could be down climbed easily to the snow. The cliffs on the left were not very tall yesterday.
