The Rockies vary in width from 110 to 480 kilometres (70 to 300mi). The Rocky Mountains are notable for containing the highest peaks in central North America. The range's highest peak is Mount Elbert located in Colorado at 4,401 metres (14,440ft) above sea level. Mount Robson in British Columbia, at 3,954 metres (12,972ft), is the highest peak in the Canadian Rockies.
passage: La Garita Mountains
Today, they are one of Colorado's lesser known, but more picturesque, wilderness areas - the La Garita Wilderness is, in fact, one of the state's original five. "La Garita means "the lookout" in Spanish, and this wilderness amply deserves the name. From the summit of this wilderness's single fourteener (14,014 foot San Luis Peak), climbers can gaze across the upper Rio Grande Valley and down the long stretch of the San Luis Valley. About 35 miles of the Continental Divide lie well above a sprawling forestland that provides ideal habitats for huge numbers of elk and mule deer.
