The Boulderfield and Keyhole, 7/3/2020


Longs Peak Conditions Report 07/05/2020

We transition into July with cool temperatures lingering on Longs Peak. We are still seeing ice formation above 13,000ft due to runoff freezing overnight. In general, the snow is melting at a consistent rate and aside from the occasional snow patch, travel to the Boulderfield is now snow free. Storms continue to bring heavy rain and hail accumulation to alpine zones on an almost daily basis, and the consistent threat of afternoon lightning storms has arrived for the remainder of the summer. Traction devices such as Microspikes or crampons and an ice axe may be warranted for certain summit routes, so please plan accordingly. 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.

The toilets at the Boulderfield, Chasm Meadow, and Chasm Junction are now open. Remember to bring your own toilet paper, and please do not throw trash into the toilets.

Keyhole Route Conditions

Summer conditions have finally arrived along the Keyhole route and all remaining snow patches can be avoided at this point. However, heavy rain and hail in the afternoons have been the norm over the last couple weeks and freezing temperatures above 13,000ft are still creating slippery conditions. Traction devices such as Microspikes or crampons and an ice axe may be warranted, depending on overnight temperatures and sporadic ice formation. Afternoon thunderstorms should be expected for the remainder of the summer, and an early ascent with return to treeline by noon can greatly help mitigate exposure to lightning. Please consider the Keyhole route as a significant undertaking with many miles of hiking and scrambling on varied terrain with extreme exposure. Altitude sickness and dehydration are common and can negatively affect one's decision making along the route. Please be respectful of the mountain and again, be prepared to turn around if the conditions exceed your abilities!

Remember your safety is in your own hands.

Chasm Crossing

The trail between Chasm Junction and Chasm Meadow crosses two sizeable snowfields. Crampons and an ice axe may be necessary to cross safely.

The rock slabs leading up to Chasm Lake tend to be wet from snowmelt and runoff. Please exercise caution on this terrain and consider trekking poles and/or traction devices for safe travel.
