🏔️ The Tango Mountains
Tucked deep into the country between Loon Creek and the Yankee Fork drainage are the rugged Tango Mountains — one of those lesser-known pieces of Custer County that most people will never see up close.
This is seriously wild country. The ridges surrounding Tango Creek and upper Loon Creek are mountain-goat habitat, with steep drainages, high rocky ridges and some incredibly remote terrain.
But what's underneath those mountains might be just as interesting.
Geologists studying the upper Loon Creek country identified a mass of pink granite near the head of Tango Creek known as the Knapp Peak stock. Within the granite they found cavities containing smoky quartz crystals, along with large milky-white quartz crystals — some reportedly reaching eight inches long.
Tango Creek eventually works its way down toward Loon Creek, connecting this high mountain country with the massive network of creeks and rivers that ultimately feeds the Salmon.
It's another reminder of just how much country is hidden beyond the river corridor we travel through — old granite, mountain goats, high lakes, unnamed ridges and miles upon miles of Idaho backcountry.
You could spend a lifetime exploring Custer County and still have places left on the map you've never seen.
