GEAR
In addition, it can still get cold and wet instantly, as is always the case in the Sierra, even during Summertime.
During Spring-Time conditions can shift to very cold and very wet very quickly.
The next danger is getting soaking wet while hiking through the snow. Shoes, pants, socks, and everything else that touches the snow.
Thus, Extra and Proper Clothing Layers that can allow us to recover our warmth, and keep us comfortable in wet conditions, are still required.
Extra layers still required.
Thus the "Spring" Gear should still be in the pack, though our "Spring" gear can be little more than our Summer gear, with the required extra layers for our proper level of safety for travel through the slick and the sloppy phases of a diminishing Spring snow pack.
Our gear should still be tailored to keep us warm while wet in snow.
FUTURE
The next heat wave should leave little more than snow remnants along the Sierra Crest.
