Flook Lake Rockhounding

• Flook Lake is an ancient dry inland sea



Flook Lake is an ancient dry inland sea with dusty alkali soil that gives it an otherworldly appearance. Situated on the eastern boundary of Hart Mountain National Antelope Refuge. Covered with sagebrushes and wild flowers, the alkaline playa is popular among rock collectors.

Agate, jasper, and occasionally fire opal can be found on the lakebed. While the minerals are not very large, they are of good quality and are naturally polished by the weather. During our trip, we discovered brown- and blue-toned agates, and jasper, which tends to be brown, red, and green.

Rock collectors are limited to surface hunting and may collect up to seven pounds per person per day. Digging with tools is prohibited. Artifacts more than 25 years old are protected by federal and state law, so removing arrowheads, flakes, rock art, or ancient and historical artifacts is illegal.

A road runs 1.5 miles through the lake flat, but it can become muddy and inaccessible during wet weather. Always check up-to-date regulations and current weather conditions before your visit.

To protect the fragile soil structure and native vegetation, please stay on the road and avoid driving off-road.

In addition to rockhounding, Hart Mountain National Antelope Refuge offers a variety of activities and sights to enjoy.

Originally established as a wildlife refuge, the area is a haven for animal observation. Visitors can often spot pronghorn antelope, California bighorn sheep, sage-grouse, and other native wildlife.

A 0.6-mile trail-less route from Flook Lake leads west to Petroglyph Canyon. Satellite images from Google Earth reveal a formation resembling a gigantic petroglyph, approximately 0.7 miles wide by 1 mile long. Additionally, you can find rock art at Antelope Springs.

Another significant site with 65 petroglyph panels is located near Petroglyph Lake. To reach it, hike 1.6 miles from the trailhead, which begins off Hart Mountain Road.

Hart Mountain National Antelope Refuge is also known for its hot springs oasis, located at an elevation of 6,000 feet. Hart Mountain Hot Springs are a collection of hot mineral springs that offer excellent soaking opportunities year-round.
