Longs Peak Conditions Report 9/6/2019

Summer is coming to an end in the high country of RMNP. Overnight temperatures are cooling off and quickly approaching the freezing threshold. Almost all of the snow on Longs Peak has melted, but water continues to drain from the mountain creating slick spots that will begin to freeze overnight. Hypothermia is a major concern on the mountain this time of year, and any storm is capable of producing sleet, hail, or even snow. Extra warm clothes, waterproof layers, extra food and water, a headlamp, personal first aid kit, and a cell phone are all strongly recommended. If you are traveling alone, please tell a friend or family member your plans and take extra care with decision making. Even a minor accident while traveling alone on the mountain can quickly turn into a serious situation. As always, please be prepared to turn around when conditions exceed your abilities.

Keyhole Route Conditions

The Keyhole route remains in “summer conditions” and is snow free. However, water continues to seep out of the mountain creating wet and slippery rock along portions of the route. Cold temperatures overnight and in the early morning hours can create ice formation, so be on the lookout for thin sheets of ice covering rock. Afternoon storms with severe lightning hazard have been the norm this summer, and retreat from the upper mountain can take several hours. Remember to check the weather forecast prior to any adventure on Longs Peak and plan on an early ascent to minimize exposure to thunderstorms.

Remember your safety is in your own hands.
