There is another big BUT because the snow quality can vary a lot more than on bumps composed of natural snow or pushed around snow on a groomed run after a lot of traffic.
During early season, there used to be snow whales in the center of the wide blue trail at Massanutten. Only took up a quarter of the width. One day I watched quite a few people think it would be fun to simply ski straight over one since they weren't that high. What they didn't realize was that those whales were very wet since they were still draining. More than one double-ejected as soon as their skis hit the backside. Included a patroller who should've known better. He wasn't going that fast, but his skis came to a dead stop.
The snow whales I've played on during early season were in West Virginia on a black at Timberline and a blue trail at Wildcat. For Timberline, one reason the whales were left that week was PSIA had training clinics happening. The trainer wanted some challenging terrain to work with. I wasn't trying to ski them as moguls since that was before I started doing Taos Ski Weeks and other lessons out west that included bumps. Mostly went down the sides to get a feel for where other people were making tracks. At Wildcat, it was fun to ski over the top. The whales weren't that high, and there was enough nice snow on both sides for a runout if I decided to skip a whale or two. In both cases, the was empty so no worries about watching for other people.
