It looks like it has quite a lot of coverage in that picture, so I would think that it either has snowmaking hookups, or they blew 2 big piles at each end and then pushed it out. As long as both Burnt Ridge and Tahawus are open, they can cover it. It is definitely nice to be able to reach the Saddle Lodge without going through the crowded main base area or relying on the glade to be open. When I skied Tahawus Glades, it always had enough coverage, but due to it being the only way to get from Burnt Ridge to the North Side, it probably had quite a bit of marginal tree skiers, so having the trail will keep the glade less crowded and the snow preserved.
I also skied Barkeater and Chatterbox glades that season. I seem to remember that they had good coverage, but I did bottom out a couple times. I do think that Gore keeps its glades better cleared than some other places because at Hunter I tried to ski the Milky Glades and I bottomed out countless times on jagged rocks (don't know how I didn't get a core shot) and I also got my skis caught under roots. I ended up back on the trail in a heartbeat.
