It wasn't the terrain of the Bird or Brighton, but it was awesome...and before the new type of ski and skiing/snowboarding the snow on Flathead/Triple Chair set up much better...pack powder, great mogul hits...and your jr High/high school friends and college friends hooting and hollering for the best mogul runs/line from the lift. This was Sundance at it's best.
The new Jake's Lift covers what Navajo gave you, but it was better and had a good midway stop for kids terrain (where the upper parking area is now...and the road back to the front of the mountain)....but even better for our ski race training from the top....we could hit two courses on upper Navajo or down Montoya, and still make it back to the midway location. Our training BYU's and USAA's was from about 6:30pm-10pm...and we skied past 10pm sometimes back then under the lights, or in the dark. Much better set up....it did have a kinda dangerous section, for kids crossing a high section. W/o a bar, it was a bad situation, though I don't know anyone who dropped.
Mandan, gave full access to that Mandan face and round the point, for good to great powder given the North facing slope....now you have to hike for it, which many of us do.
I guess the parking area is necessary, but the lift designs were much better and still gave quick access to the back mountain.
Finally, they really should have a Catwalk/track from the parking to the bottom and there's room to do this.
Management of that mountain hasn't been historically great, but then again, that's part of the appeal. I hope it doesn't lose it's quirkiness since Redford sold.
