Mount Redoubt
steep-sided volcanic cone about 10 km in diameter at its base
Redoubt Volcano, or Mount Redoubt (Dena'ina: Bentuggezh K’enulgheli), is an active stratovolcano in the largely volcanic Aleutian Range of the U.S. state of Alaska. Located at the head of the Chigmit Mountains subrange in Lake Clark National Park and Preserve, the mountain is just west of Cook Inlet, in the Kenai Peninsula Borough about 110 miles (180 km) southwest of Anchorage. At 10,197 feet (3,108 m), in just over 5 miles (8.0 km) Mount Redoubt attains 9,150 feet (2,790 m) of prominence over its surrounding terrain. It is the highest summit in the Aleutian Range. In 1976, Redoubt Volcano was designated as a National Natural Landmark by the National Park Service.
Active for millennia, Mount Redoubt has erupted four times since it was first observed: in 1902, 1966, 1989 and 2009, with two questionable eruptions in 1881 and 1933. The eruption in 1989 spewed volcanic ash to a height of 45,000 ft (13,700 m). It caught KLM Flight 867, a Boeing 747 aircraft, in its plume. After the plane descended 13,000 feet, the pilots restarted the engines and landed the plane safely at Anchorage. The ash blanketed an area of about 7,700 mi2 (20,000 km2).
Begin with the source’s own compact description: “Mount Redoubt” is steep-sided volcanic cone about 10 km in diameter at its base. The dossier treats that line as a proposition to test through Mount, Redoubt and steep-sided, not as a finished interpretation.
Why this record matters
The phrase “steep-sided volcanic cone about 10 km in diameter at its base” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 15, 2026. The linked authority identifier is Q840735. VIAF identifies the subject as 315131183. The Library of Congress control number is sh90005214. Authority coordinates are 60.485, -152.743. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1976, 1902, 1966 and 1989.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
