The Wells Gray-Clearwater volcanic field, also called the Clearwater Cone Group,[2] is a potentially active[3] 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.[4][5]

Most of the Wells Gray-Clearwater volcanic field is encompassed within a large wilderness park called Wells Gray Provincial Park.[4] This 5,405 km2 (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.[4] Five roads enter the park and provide views of some of the field's volcanic features.[4] Short hikes lead to several other volcanic features, but some areas are accessible only by aircraft.[6]
