Yeah crowds were pretty tame for a day like this. The lift line at the end of the video was relatively short, less than 10 minutes, and that was the longest line I waited in all day (aside from the ~20 minutes spent waiting for the top to open).
I got 6 runs of "first tracks" where I was within the first half-dozen people, and another 4 of tracked but still good runs. This was possible because good terrain opens piecemeal at Mammoth on a day like this. For some context, every edit/cut in the video is a different lap.
First thing in the morning I went to chair 22 and was on about the 12th chair up. The line on 22 was slow to build up, so I got a second good lap there before going over to wait for the Gondola. I waited about 20 minutes and got in the 5th gondola up, netting me first tracks on Climax. Chair 23 opened shortly after the Gondola, so I traversed straight there and was on an early lift there as well to Drop Out. After a second lap on 23 out to Monument (bad call, thin cover, Paranoinds were better) we ended up at the bottom Gondola, which had a 5-7 minute line. When we got to the top, Dave's had just opened (pure luck on that one) so we got early tracks there. Since Dave's was finally just opening, Chair 9 was also starting to spin, so we went straight there after Dave's. With the light traffic on the hill, traversing out the the Tail netted 4 laps of good snow before our legs were cooked and the trees were well tracked. If I was in better shape like Staley, I'd have headed over to the backside to hike Hemlocks at that point. But in a fairly unspectacular season, I was quite satisfied with the day as it stood.
