The road is very dusty and the most common vehicles are tourist busses. Here you see a bus moving down the road and kicking up a cloud in its wake.
There is one road through Denali National Park. It is only open to busses. This is a section of the road seen in the distance. The cloud of dust is a passing bus. (GPS coordinates are approximate.)
Almost looks like this rock bounced a couple of times before landing in the field. Taken from Polychrome overlook on the Denali Park Road.
