Longmire Village and the Cougar Rock, Ohanapecosh, White River, Ipsut Creek, and Sunshine Point frontcountry campgrounds are all vulnerable to geologic hazards. Although eruptive events are usually preceded by an increase in earthquake activity, other geologic hazards (e.g., debris flows and glacial outburst floods, with the added hazard of rock fall at White River campground) can occur without warning.
Park employees and visitors may have insufficient warning to safely leave the area should an event occur. Although Longmire and the frontcountry campgrounds will be open for use according to the posted spring opening schedule, individuals must decide if they will assume the personal risk of spending time in these potentially dangerous locations. If you choose to stay, be sure to review posted geologic hazard, evacuation and escape information.
