STORM AND COOL TEMPS DELIEVER ALPINE CONDITIONS TO THE HIGH COUNTRY July 28, 2015

Just as the high country was drying out, the crampons and ice axes hung up, a cold front hit the Tetons last night with low temperatures, snow and rain. Game on!

Snow was sticking at the 9,500 foot level. Winds blew up to 70 miles per hour at the Grand Teton's Lower Saddle and according to our favorite weather source, MountainWeather.com, at one point last night when the temperature dropped to 25 degrees and the wind was blowing steady at 40 mph, it felt like 7 degrees.

Temperatures are expected to increase during the day but evening temps will remain cool, so it remains to be seen how quickly things dry up versus turning into verglas.

This is the busiest time of year in the Tetons. Remember that hikers can get backcountry permits in Moose and Colter Bay. It is just climbers and those bound for Garnet Canyon that must come to the Jenny Lake Ranger station.

ALPINE CONDITIONS CONTINUE IN THE HIGH COUNTRY- July 19, 2015

Storms continue to roll through the Tetons creating and maintaining alpine conditions like snow, ice and verglas. In periods of extended, unsettled weather such as we're currently in, it's important to continue studying the past, present and future weather conditions. What fell as rain or snow may quickly turn to verglas. What is iced up today could be dry tomorrow. Remember that rockfall hazard increases with precipitation. Keep an eye to the sky, stay mindful that conditions are constantly changing up high and come prepared for anything.

STORMS DELIVER ICE & SNOW TO THE HIGH ELEVATIONS - July 14, 2015

Storms from the past week have left ice, verglas, and some snow above roughly 12,000'.  While the sunny ridges and aspects dry quickly, the shaded terrain and nooks and crannies of the Grand still hold these alpine conditions.  Crampons are recommended, particularly for the Owen Spalding route.

ROCKFALL ACTIVITY INCREASES IN HIGH COUNTRY - July 7,2015

Rockfall activity in the Teton Range has increased significantly with the recent rain showers and thunderstorms we have been receiving.  Specifically, rockfall injured a climber near the base of the Dike Route on the Middle Teton today, and we have received multiple reports of major rockfall on Nez Perce.  Hikers and climbers should remain extra vigilant and cautious while traveling underneath steep rock faces or couloirs, especially after rain events.
