Significance

Nestled among 14,000-foot peaks, Telluride is cradled in a wide valley that, until now, remained as verdant and peaceful as when the Ute Indians hunted there centuries ago. But sprawl has come to the mountains, and now a massive resort may be developed on the 880-acre valley floor, threatening the region's historic context and forever altering one of the Rocky Mountains' last intact mining towns.
