This the Mammoth Mountain snow report for the end of March and it really feels like it is the end of April with weather in the Mid-50's and even breaking into the 60's. Even though we haven't had much snow lately, it is hard to complain about sunny days with no wind.
The snow coverage is still pretty good with a little bit of rock dodging needed and a few bare dirt spots here and there. That being said, 100% of the mountain is still open and 90% of the open runs still have pretty good snow. Expect it to be pretty hard early in the morning, softening up very quickly, and then turning to slush on most of the mountain by noon. Stay at the higher elevation lifts and spend most of your time over towards The Mill and Main Lodge for the best snow.
The nice thing about slushy snow is that it opens up the whole mountain. Pretty much anything off trail is skiable/rideable as the snow softens up, so hit up Climax or Dave's run for some steep turns late in the afternoon. You can also find some really good groomers on the less busy runs, so make sure you cruise around a little to find some untouched corduroy. The best suggestions I have for warm weather riding is get a good wax and go a little earlier in the day.
The terrain parks are still going strong with tons of fun features. You will find two huge kickers in main park along with a ridiculously huge half pipe and several expert level rails. Forrest trail has a couple medium jumps and jibs to play around on and chair 4 park has several fun flowy lines including a couple good size jumps. It gets pretty tough to keep your speed starting around noon, so get a good wax and go early. Later in the day you can even see the dirt coming through the snow, but it's still a good time out there. See you on the hill.
