Lake George and Its Amazing Floods
Near the Knik Glacier, there's a special lake called Lake George 61°15′00″N 148°37′00″W / 61.25000°N 148.61667°W. This lake was so unique that it became a National Natural Landmark.
Lake George was famous for something called a "jökulhlaup". This is an Icelandic word for a "glacial lake outburst flood." Imagine a giant ice dam holding back a huge amount of water. When this ice dam broke, it would send a powerful wave of water, ice, and rocks rushing down the river valley.
These floods happened every year! They could cause a lot of damage to homes and farms nearby. However, the jökulhlaup stopped happening in 1967. Scientists believe this was because the glacier started to shrink. This change might have been linked to the massive Good Friday earthquake that happened in 1964.
A Look Back in Time
Early settlers in the area used to have a yearly lottery. They would guess the exact date when the jökulhlaup would break and flood the Knik River Valley. These floods often blocked important roads between Anchorage and the Matanuska-Susitna Valley. This made travel very difficult for people living there.
Knik Glacier in Movies
Did you know Knik Glacier has been in movies? In 1991, Paramount Pictures filmed part of Star Trek VI: The Undiscovered Country here. The glacier was used as the icy alien planet prison, Rura Penthe. Captain Kirk and Dr. McCoy were rescued from this planet in the movie!
The glacier also appears in Lauren Daigle's music video for her song Rescue. It makes a beautiful backdrop for the video.
