Mount St. I can't remember

So, on the first full day in California, we took the Palm Springs tram to the top of the mountain and did a little "hiking" up there. It was about 25-30 degrees cooler at the top, which my dad said is really noticeable when it is 114 degrees in Palm Springs, but I noticed it quite a bit with the temp only being 100. It was nice to walk around. They had lots of pictures of people playing in the snow (in the winter of course). I hadn't really thought about there being snow in southern CA, but I guess they have everything there, right?
