The Sierra Club has joined seven other environmental groups that filed a lawsuit last week against a mountain bike park at Timberline Ski Area on Mt. Hood. Plans for the 17-mile trail network have been in the works since 2010 and were approved by Mt. Hood National Forest Supervisor Christopher Worth this past November.
The groups say the trails are likely to increase erosion and disturb wildlife, as well as interrupt other forms of recreation, like hiking. Timberline, on the other hand, sees the plan as an opportunity to appeal to a growing number of mountain bike enthusiasts.
When the proposal first appeared in 2010, another group filed a similar lawsuit, which was dismissed when the U.S. Forest Service found that the park would cause “no significant impact.” Many of those groups chose not enter this lawsuit.
