the map is 6 mo old from the description in the link i posted the upper part of grand prize is open
"Motorized Use: No roads that are currently open to vehicles, or trails that are currently open to two wheeled motorized use would be closed. The Grand Prize and Germania trails (including the ridge in between) and the Frog Lake Loop would be excluded from wilderness and remain open to two wheeled motorized use under the existing SNRA travel plan. The following higher elevation snowmobiling areas would remain open as allowed under the existing SNRA travel plan: 4<sup>th</sup> of July Basin, Washington Basin, Phyllis Lake Basin, Champion Lakes and Warm Springs Meadows."
or am i missing something. as the grand prize area is one of my favorites for later in the year. (you have to cover 8' tall rocks all over the place)
