The landslide is about 500 feet (150 meters) long and contains an estimated 30,000 cubic yards (23,000 cubic meters) of material, Karpilo said. Many of the soil blocks that fell are up to 80 percent ice, a feature of the permafrost found in Denali. The slide was probably caused by permafrost melting, Karpilo said.
"You're just going to have more and more mud coming down, so it's going to be a constant battle" to keep the road open, he said.
Karpilo hopes to be able to repeat the road photography project to track change over time. An annual record would be great, he said, though at least every five to 10 years would also be useful. The cameras could also be mounted on a backpack or a river raft to reach remote areas, Karpilo said. A record of the Grand Canyon, for example, could help park rangers deal with invasive species.
"It'd be cool to have kind of a Google Street View system go down the river," Karpilo said.
Google River View? Better hope Google CEO Larry Page doesn't get there first.
