Inside the west entrance of West Ice Cave, a lava tube located in a deep collapse pit south of Medicine Lake, California.  The cave starts w/ a crawlway into a room w/ a level ice pond that has some floating liquid water on top.  Past a squeeze through two large breakdown boulders is this view where the ice drops into a frozen slide a good 15 feet down before sloping additionally further down, reminding me a bit of Crystal Ice Cave in Lava Beds National Monument.  A rope was handy to have as well as microspikes - there is no other exit once you descend.  The rope I tied to a leftover chain - an old chain ladder led the way down but it was already long buried under a foot of ice.  The ice here has accumulated for centuries I would imagine as I cannot see the breakdown floor below.  There are small rocks that broke off the walls that are embedded as islands in the ice, almost resembling little nunataks.  Ceiling height is highest here at nearly 20 feet up.
