The above picture is of the Denali Park Road at the Pretty Rocks formation last August. That was the last time any gravel had been dumped in this section of road that is dropping due to melting ice under the roadbed.
This spring, maintenance crews discovered that the road had dropped as much as 40 feet at the troublesome section near Pretty Rocks. It had already been decided that the park road would be closed for the 2022 season due to the roadbed situation, but the drop was more impressive than forecast.
A new bridge will be installed over the section with the melting ice formation, and will be secured into solid rock on either side of the great melt. I expect that the road into the heart of Denali Park to remain closed through the 2023 season.
