Once again, I’m chasing the retreating ice. More often than not, there is now a kayak pulled up on the rocks after I’ve walked all the way out. It would be a lot quicker way to arrive than on foot!
In this case, this group arrived in a pair of kayaks and settled in for lunch before doing their exploring. The “rock” they are on is actually a gravel-covered block of ice. The ice will melt over the next couple of months, leaving only a pile of sand and gravel. The fall rains and winter snow will probably wash the remaining sand down into the lake by spring.
The area of darkened ice on the face of the glacier is an area where the under-ice river flows out into the lake. The in-rushing water is leaving ripples in the otherwise still lake.
