My Yamaha Grizzly 700 SOTA steed at the top of (end of) 12M29. This is the DIAMOND_458 point on my maps and is at 40.31118N, 120.67452W. From here it is a cross-country hike (no trail) of 1.16 miles to the summit as per my GPS track log, with an elevation gain of around 460 feet per the USGS topo map.
