To the west Fish lake wilderness covers all peaks to Richfield, UT and its local surroundings. To the east, all peaks to Capitol Reef National Park. If your range is west of that, feel free. Otherwise please do not author a new page. Please do not post a page on a peak you have not summited or visited.
I don't think there's such a place as "Fishlake Wilderness." There is the Fishlake National Forest, though. As for the region labeled as the "Fishlake Wilderness," I think it would be fair to call it the High Plateaus of Central Utah. There is the Fishlake Plateau, Thousand Lake Plateau, Awapa Plateau, and Aquarius Plateau. The Sevier Plateau and Wasatch Plateau are further removed from this central plateau region by distance and large changes in elevation so they likely shouldn't be included.
