Here's my final posting on the exploration of the middle branch out of the Crows Foot on the Madera Sugar Pine. I've drawn a rough map of the spurs off the line. You can reference this to the Donald DeVere map on page 50 of Johnston's Thunder in the Mountains:
You can see there were numerous spurs that were not mapped, and one spur that appears on the DeVere map near Crow's Foot and Signal Peak but I cannot find a trace of. I'll continue to explore this area of summer and will psot my finding at a later date. Hope all enjoyed the adventure...
