Longs Peak Conditions Report
8/24/2025

Fall is just around the corner, and the environment on Longs Peak is beginning to change. Recent storms have brought a combination of rain, hail, sleet, and snow, creating a wide variety of conditions on the mountain. Heavy rains combined with cooler temperatures have left the mountain wet and fragile, with numerous reports of fresh rockfall and early season ice formation occurring. In addition, afternoon thunderstorms remain a real threat and a return to treeline by noon is recommended to help mitigate exposure to lightning storms.

Traction devices such as Microspikes, Yaktrax, or crampons and an ice axe may be prudent for travel on the upper mountain depending on the route chosen. 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.

Remember your safety is in your own hands

Chasm Crossing

The trail between Chasm Junction and Chasm Meadow crosses a steep slope known as Chasm Crossing. This slope is snow free and can be traveled entirely on dry trail. The rock slabs just below Chasm Lake are steep and tend to be wet with runoff, so trekking poles and cautious footwork are advised in this terrain.
