Baxter’s Pinnacle and its southwest descent gully have been closed due to an active peregrine falcon nest. Baxter’s Pinnacle is a popular climbing route in Cascade Canyon at Grand Teton National Park. Park Spokesperson Jackie Skaggs says the route is easily accessed from the mouth of Cascade Canyon and so it is very popular – particularly for people preparing for the climbing season. Skaggs explains that a peregrine falcon pair established a nest near Baxter’s Pinnacle in 2011 making this the second year that a closure has been levied to protect both falcons and climbers. Skaggs says climbers have reported being dive-bombed by the birds as they seek to protect their nest and their young. Seasonal and temporary closures for wildlife protection are common in Grand Teton to protect both wildlife and park users. Entering a posted wildlife closure is a violation under the code of federal regulations that can result in a citation and fine.
