We boondocked at a great site in October 2020 near Mill Creek Wilderness, dirt forest roads not too bad but we have a pretty low bar. Some great views looking west/northwest. Boondocking near the Big Summit Prairie was a lot more difficult. Roads narrow and rough with hardly any place to pull off. We finally found a flat spot near the southeastern end but would not do it again.

First three pics are of spot on the northeastern corner of mill creek wilderness, the last photo near southeastern corner of big summit prairie.
