Southeast’s tall young mountains, giant earthquakes, green rainforests and large bears have kept University of Alaska geologist Dan Mann coming back for nearly half a century.
Denali National Park is still melting out from its snowiest winter season in 99 years of record keeping.
A slumping section of the Denali National Park road dropped an unprecedented amount over the winter, leaving a 40-foot drop in the road near Polychrome Pass.
Twenty-five million dollars in funding for the project comes from the federal infrastructure bill that passed late last year.
The National Park Service is looking at building a bridge over the landslide.
A melt-caused landslide is accelerating, prompting action to maintain the route used to transport thousands of visitors through the park every summer.
A thawing rock glacier underneath a 100-yard section of the road going through Polychrome Pass is causing the road to slump.
The park service says the Pretty Rocks landslide, located around Mile 45, has required increasing maintenance in recent years because it is changing rapidly due to climate change.
Officials are studying whether the existing path of the park’s 92-mile road can be spared from a creeping landslide. Scientists say it could be a preview of Denali’s future as permafrost thaws.
