It’s been a busy construction season in Grand Teton National Park, but not just on the park’s roads. Some of the wildlife has been rather industrious as well. Over the past several months, a family of beavers built a sizable dam and lodge in a wetlands area along the Moose-Wilson Road just north of the Death Canyon Road. The beavers expanded their dam and created a substantial pond that threatens to completely flood the road and cause structural damage. In an effort to lower the water level in the pond and reduce flooding, park employees will modify a previously installed flow device that allows for water to gently pass through the dam. During the work, a temporary closure of the Moose-Wilson Road in Grand Teton National Park will be imposed from 2:00 pm Monday until 8:00 am Tuesday. The closure will span between the Death Canyon Road junction and Teton Park Road in Moose. During this closure, through travel will not be possible. Visitors can still reach the Laurance S. Rockefeller Preserve and Death Canyon trailhead from the Granite Canyon entrance station.
