About Ingakslugwat Hills
Ingakslugwat Hills is a volcanic field rising to 190 meters (623 feet) in United States's North America Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Ingakslugwat Hills is located in United States, within the Northern Alaska-Bering Sea Volcanic Province of the broader North America Volcanic Regions. Situated at 61.43° N, 164.47° W in the Northern Hemisphere, the volcano lies within a subarctic climate zone. At just 190 meters above sea level, Ingakslugwat Hills is a relatively low-elevation volcanic feature. Despite its modest height, it remains an active geological formation with the same underlying magmatic processes as its taller counterparts. The volcanic landform is characterized as a cluster, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Ingakslugwat Hills is an intraplate volcano, meaning it formed away from any plate boundary. These volcanoes are often powered by hotspots — plumes of abnormally hot mantle material rising from deep within the Earth. Hotspot volcanoes like Ingakslugwat Hills tend to produce effusive eruptions with lava flows that can be relatively predictable, giving nearby communities in United States more time to prepare. However, they can also produce explosive phases, particularly when magma interacts with groundwater. The dominant rock type is basalt / picro-basalt, a dark, fine-grained volcanic rock that forms from rapidly cooling, low-viscosity lava. Basaltic eruptions tend to be less explosive and produce fluid lava flows that can travel long distances. While less immediately dangerous than explosive eruptions, basaltic lava flows can destroy structures and infrastructure in their path, and volcanic gases released during these eruptions can affect air quality over a wide area.
GVP Reference Summary
The Ingakslugwat Hills consist of at least 32 small cinder cones and eight larger craters covering more than 500 km2 in the Yukon-Kuskokwin delta area of SW Alaska. Numerous small spatter cones and cinder cones range from 8 to 190 m in height; many are concentrated in the NW side of the volcanic field. The latest activity was considered to have occurred during the Holocene (Moll-Stalcup, in Wood and Kienle, 1990). One low cone containing a 400-m-wide lake may be a maar. This dominantly alkali olivine basaltic field also contains basanitic and nephelinitic rocks, some with inclusions of lherzolite and layered gabbro.

Frequently Asked Questions About Ingakslugwat Hills
Is Ingakslugwat Hills an active volcano?+
Ingakslugwat Hills is classified as active based on credible evidence of past eruptions. Although its last known eruption was in prehistoric times, volcanologists consider it capable of erupting again.
How high is Ingakslugwat Hills?+
Ingakslugwat Hills has a summit elevation of 190 meters (623 feet) above sea level. At 190 meters, it is a relatively low-elevation volcano.
What type of volcano is Ingakslugwat Hills?+
Ingakslugwat Hills is classified as a Volcanic field. Volcanic fields consist of clusters of small volcanic vents and cinder cones spread across a region. Rather than a single central vent, eruptions can occur at many points across the field.
Where is Ingakslugwat Hills located?+
Ingakslugwat Hills is located in United States, in the North America Volcanic Regions. More specifically, it lies within the Northern Alaska-Bering Sea Volcanic Province. Its exact coordinates are 61.430° latitude, -164.470° longitude.
Is it safe to visit Ingakslugwat Hills?+
Ingakslugwat Hills can generally be visited, but as with any volcano, visitors should check local conditions and any advisory notices before traveling. United States may have specific regulations for accessing volcanic areas. Guided tours are often the safest and most informative way to experience a volcano.
