I don't have any experience with a Pacific yurt but they do have about ten of them at Yosemite Lakes Campground and I know they have done well there. The elevation is only about 4000 feet. We do get three to four feet of snow there.
I have several yurts that are unoccupied during winter and when the sun comes out they warm up and the snow will sluff off.
I set one up on Donner pass this summer. It is at 7,000 feet and they are putting a support under the hub. They expect ten to fifteen feet of snow. It will be unoccupied most of the time. I will be able to tell you how that goes in Spring.
