Flight Over Denali
When we flew over the Denali Park Road, I knew we were close to the mountain itself.
I recognized the glacial morrain of the Muldrow Glacier from pictures I had seen in the past fiew days. A glacier piles up mounds of debris called a morrain at the end of the glacier if it ends by melting in a valley. I knew Denali was at the top of that Glacier!
Our flight path now parallels the morrain of the Muldrow Glacier.
We are reaching the place where the flow of the ice meets the morrain.
Further up the Muldrow Glacier you get the krinkling effect of the forced flow, producing the large crevasses. The snow deepens with the rising elevation. Notice the recent avalanche scour on the mountainside.
As the mountains rose, great mounds of snow cover them.
