Teewinot Mountain (12,325')

The name for this salient peak was bestowed by the first-ascent party.  Tee-Win-At, as it was originally spelled, is, according to the first-ascent party, a Shoshone word meaning "pinnacles."  This peak is certainly one of the most important of the Teton peaks both in placement and in size.  From the Jenny Lake Visitor Center this mountain is the highest visible, and some visitors mistake it for the Grand Teton.  Although a long climb of 5,600 feet, Teewinot is one of the more popular peaks.  

Many accidents and fatalities have occurred on Teewinot's East Face. In spring, this challenging, steep snow face typically develops deep, hazardous runnels and inconsistent snow quality is commonly encountered. Solid ice axe and crampon skills are essential.

The East Face scramble is listed as a Class IV . But in actuality, the moves near "the choke" and the final moves to the summit are more like 5.4 with significant exposure. It is easy to get off route into more technical terrain that requires a rope and protection.
