Surprise Valley is a valley in extreme northeastern California, about 60 miles in length from north to south. Locals refer to the area as the Tricorner Region because of the region's location at the intersection of California, Oregon, and Nevada state lines. The valley is east of the Modoc County seat of Alturas. The area is part of the Great Basin which extends across most of the northern half of Nevada. Terrain Most of the valley is over 4,000 feet above mean sea level (AMSL), and could be characterized as a high altitude desert valley. A series of alkaline lakes occupy low-lying areas. Forested mountains mark the west side of the valley. The Hays Canyon Range, (mostly east of the Nevada state line) is to the east, and the Warner Mountains border the west. The valley is considered part of the Great Basin, a desert region roughly covering the geographic majority of Nevada and extending into Utah; also regions of southeast Oregon, and southern California, in the east. Communities in Surprise Valley include Eagleville (ZIP Code 96110), Cedarville (96104), Lake City (96115), and Fort Bidwell (96112). Visiting Most of the land west of the main north-south highway, Surprise Valley Road, is US Forest Service land. To the east of the road, most land is owned by the Bureau of Land Management (BLM). Recreational facilities on BLM lands tie in with the US Fish and Wildlife Service, Sheldon National Wildlife Refuge, Nevada (formerly called Sheldon Antelope Refuge). Over the region, opportunities for hiking, exploring dirt roads, birding, stalking antelope with cameras, fishing, camping, and mountain biking are available. Big game and bird hunting is popular among some area visitors. A BLM brochure warns, "Snowstorms occasionally strand travelers. May and June snowstorms are not uncommon." There are hot springs and abandoned mine shafts throughout the region. Transportation Two gas stations exist in Cedarville. One (Rabbit Trax) is attended normal business hours, the other not normally attended. Both accept cards to pump any time. Additionally, there is a Tesla Destination Charger at The Cottage at Winjes Farm, which is located on Surprise Valley Road.
