A narrow curvy road to Betty Jumbo Mine
Betty Jumbo Mine is an abandoned tungsten mine at an elevation of 2.219m (7,280ft) above the sea level, located in Inyo County, in the US state of California.
Nestled in the Inyo Mountains, within the Inyo National Forest, the road to the mine is an old mining road. It’s called Forest Service Betty Jumbo Mine road (36E401). It’s very curvy and hairpinned following a narrow road that precipitously snakes its way along the side of the Inyos with a lot of steep, rugged mountainside. 4wd vehicle required.
The road is pretty steep. Starting from the Mazourka Canyon Inyo County Road, the road is 11.90km (7.4 miles) long. Over this distance the elevation gain is 762 meters. The average gradient is 6.40%. The road is subject to rock fall: frequent large, fallen boulders lay across the middle of the road.
