Continuous grade with loose gravel on the first 1/2 mile, gradually becomes flowy single track, some rocky sections, but still 100% rideable if you have an ebike or really strong legs.

Significant amount of major deadfall. Gave up after about 8 just in the second mile. Also, with Jardine completely dry, I assumed there wouldn't be much snow. I was wrong

Not closed. In great shape. A little overgrown at the top and bottom, but the pines in the middle are glorious!
