This piece of petrified wood got me curious about what was along the contact of the granites and Relief Peak formation. See the "Geology" folder for all of…
This series of images were taken to document geology of interest to me for later study. Walking along the eastern shore of High Emigrant I often find remnant…
Typical Relief Peak porphyritic andesite with big-ol' hornblende crystals.
The entirety of High Emigrant Lake from the southeast shore. Big Sam on the right. The entire eastern shore is a contact between the granodiorites and basal…
The yellow flowers are called Gordon's Mousetail, thanks to an iNaturalist inquiry.
Big erratic.
But under the large erratic were these amazing beds of conglomerate!
Everything from rounded to subrounded clasts in this conglomerate seemed to be cemented together with an angular breccia. Perhaps this was a violent mudflow…
Flowers and a conglomerate.
More angles of the conglomerate.
Chunk of porphyritic andesite that was also part of a mudflow. Check out the rind of matrix on the top.
Toes for scale of this good sized cobble that had obviously been rounded in a river in one point of its life.
The hallmark of this conglomerate at the base of the Relief Peak fmt is all of the chunks of oxidized petrified wood and molds of wood that can be found as…
Crappy pic, but GPS tagged for future reference.
One of the features that caught my attention from across the lake were these large columns. It turns out they are composed of vesicular andesite (or something…
Gordon's Moustail growing amongst oxidizing columns of andesite.
The columns lie directly atop the conglomerates.
Me for scale. The columns are about four feet tall.
Tumbling, crumbling columns.
One of my favorite views from the entire trip. Weathered columns of the columns made of vesicular andesite with lots of wildflowers growing.
