Jennifer and I had only gotten a short stay in Mammoth when we were able to fly there for a half day 2 days ago. I had really wanted to go back since then, and in a faster plane this time. In a Cirrus SR22, it took 1.2h of flight time in each direction.
We flew there saturday morning, picked up the rental car in Mammoth, and were on the slopes by 10:30, in time for the icy snow to be nice corn snow.

Hello Mammoth, we're landing and we'll be back in a minute

The snow coverage was still pretty good considering, although considering the warm temperatures, it's probably going to melt fast now.
I took Jennifer around all the lifts and the entire mountain over the two days we were there. As long as we stuck with the sun during the day, the snow was actually fairly decent.

The weather was so nice, that a bunch of college students crowded the mountain in bikinis and swimmers, even at 11,000ft (3000m), which was definitely fun to see. I don't even think they got too cold :)

For the first day, we ended up doing the side of the mountain on the side
of Canyon Lodge.

While the base lodge is a clusterfuck to park at (their parking lot is a joke, and you have to park down the street, quite a ways away), the main lodge itself was nice, and it had the famous Mammoth of course.

We ended up not parking by the main lodge, and by Mill's Café, which is midway on the mountain, and by the Stump Alley/Gold Rush Express lifts going on both sides of the mountain. When the sun allowed, we checked out the other side of the mountain and the back side for our second day.

By sunday late afternoon, we had covered a combined 80 miles of terrain (120km) and used all the lifts that went to terrain (we skipped a few baby lifts).
I was pooped, so we drove back to the airport around 15:30, and had another 1.2h flight with a few nice views of Mammoth on the way home. We were back home after 2h45 from when we left Mammoth (which included rental car return, loading/unloading the plane, and driving to and from the airport), so it wasn't too bad considering, and definitely beat the otherwise 6.5h drive.
And if you'd like it, here's the GPS track of the two days in Mammoth .
