Guides and organised ascents
For remote mountain terrain and challenging conditions, engaging a professional guide is advisable. In the United States, the national mountain guide association is the American Mountain Guides Association, which is an IFMGA/UIAGM member, alongside the national alpine club, the American Alpine Club. Established guiding companies working within the country include RMI Expeditions based in Ashford, Washington, and Exum Mountain Guides based in Moose, Wyoming. Visitors should note national permit rules, as some peaks in the United States require climbing registration or permits from the land agency, such as Denali requiring registration at least 60 days ahead and Mount Rainier requiring permits on glaciers or above high camps.
Safety and preparation
Climbing or hiking in the remote terrain of Anvil Peak demands careful preparation, self-reliance, and proper gear to cope with rapid weather changes and low temperatures. In case of an emergency, the general emergency number in the United States is 911, which connects callers to dispatchers who alert the local search and rescue team, usually run by the county sheriff or national park service.
