Widespread deep slabs in ralston cirque

We toured from camp sac up to ralston summit with intention of skiing something on north side of ralston and continuing on to echo

From the summit of ralston we saw evidence of a widespread, deep slab cycle that looked like it likely occurred near the end of the high precip intensity.  We noted at least 6 large slides on N and NW slopes between 7500 and 9000 ft. Almost every path on this aspect and elevation between ralston and talking mtn had large crowns.  The size, fracture character, and impressive propagation all suggested deep persistent avalanches

we altered our descent route based on our new obs, and observerd no other instabilities old or new on our ascent and descent of echo
