Effusive eruptions involve a relatively gentle, steady outpouring of lava rather than large explosions. They can continue for years or decades, producing extensive fluid mafic lava flows. [43] For example, Kīlauea on Hawaiʻi continuously erupted from 1983 to 2018, producing 2.7 km 3 (1 cu mi) of lava covering more than 100 km 2 (40 sq mi). [44]
The use of profanity in films has often been controversial, but has increased significantly in recent decades. [1] [2] The word, fuck, is repeatedly used for the documentary film of the same name. [3]
The lava field reaches southeastward from the Pioneer Mountains. Combined U.S. Highway 20–26–93 cuts through the northwestern part of the monument and provides access to it.

One of the best preserved flood basalt areas in the continental U.S. contains three lava fields along the Great Rift of Idaho. Among the volcanic cinder cones, lava tubes, and fissures created 15,000 to 2,000 years ago is the world's deepest open rift crack. The adjoining National Preserve protects an additional 410,000 acres. [73] [74]
The Hell's Half Acre lava plain is located in Bingham and Bonneville counties in the state of Idaho. The site is about 150 square miles (390 km 2) in size. [1] The area where a former lava lake existed is marked by a 875-yard (800 m) long by 328-yard (300 m) wide depression near the summit of the lava field. [7]
National Creek Falls is located on pumice flanks of Mount Mazama with basalt outcropping that diverges the creek into a wide waterfall. The National Creek Falls trail starts off Crater Lake Highway and descends through a shaded, mixed conifer forest, ending at the base of National Creek Falls, totaling 0.75 mi (1.21 km).
