This ten-year-old nonprofit helps preserve environmental giants by enlisting volunteer crews to rebuild trails, pick up garbage and generally buff up Colorado's biggest, and often most used, peaks. Last year, Mount Massive (14,421 feet), south of Leadville, and Wetterhorn Peak (a puny 14,015 feet), near Lake City, got makeovers. Volunteers don't get paid, but they do get equipment, food and a lofty sense of satisfaction.
