Wells Gray Provincial Park in the context of Northern Rocky Mountains Provincial Park

The Wells Gray-Clearwater volcanic field, also called the Clearwater Cone Group, is a potentially active monogenetic volcanic field in east-central British Columbia, Canada, located approximately 130 km (81 mi) north of Kamloops. It is situated in the Cariboo Mountains of the Columbia Mountains and on the Quesnel and Shuswap Highlands. As a monogenetic volcanic field, it is a place with numerous small basaltic volcanoes and extensive lava flows.

Most of the Wells Gray-Clearwater volcanic field is encompassed within a large wilderness park called Wells Gray Provincial Park. This 5,405 km (2,087 sq mi) park was established in 1939 to protect Helmcken Falls and the unique features of the Clearwater River drainage basin, including this volcanic field. Five roads enter the park and provide views of some of the field's volcanic features. Short hikes lead to several other volcanic features, but some areas are accessible only by aircraft.

Helmcken Falls is a 141 m (463 ft) waterfall on the Murtle River within Wells Gray Provincial Park in British Columbia, Canada. The protection of Helmcken Falls was one of the reasons for the creation of Wells Gray Provincial Park in 1939.

There are six other waterfalls on the Murtle River, upstream from Helmcken Falls. The others are The Mushbowl, Dawson Falls, Majerus Falls, Horseshoe Falls, Meadow Falls and McDougall Falls. Only Helmcken, The Mushbowl and Dawson can be reached by road. Majerus, Horseshoe and McDougall Falls are accessed by trails. Meadow Falls is very difficult to view, except by air.

The Clearwater River is the largest tributary of the North Thompson River, joining it at the community of Clearwater, British Columbia. The Clearwater rises from glaciers in the Cariboo Mountains and flows in a mostly southerly direction for 201 km (125 mi) to the North Thompson. Its entire course, except the last 5 km (3 mi), is within Wells Gray Provincial Park. Its confluence with the North Thompson is protected by North Thompson River Provincial Park.

There are two large lakes on the Clearwater River. Hobson Lake is 35 km (22 mi) long and averages 1.5 km (0.9 mi) wide. Clearwater Lake is 24 km (15 mi) long and averages 2 km (1.2 mi) wide. The Clearwater's largest tributaries are (from source to mouth) Hobson Creek, Goat Creek, Lickskillet Creek, Azure River, Falls Creek, Murtle River, Mahood River, Hemp Creek, Grouse Creek, and Spahats Creek.
