I am looking for DEMs of the northern Ray Mountain area
about 90 km south of Bettles, Alaska, at latitude 66 degrees,
07'N, and longitude -151 degrees, 23'W, in the northern
Ray Mountains. I have looked at the National Map
Seamless Server and other likely sources and found none.
The Seamless Server tells me that there is “not any
available products in the area indicated” for all the NED
options listed.

Does anyone know where I might find small-scale DEMs
for this part of the Ray Mountains, which show more
topographic detail than the 3-arc second 1x1 degree
1:250,000 scale Defense +Mapping Agency DEMs. I am
looking at the geomorphology of landforms in the Ray
Mountains and relationship to underlying geology and
having detailed DEMs to work with in Global Mapper
10.0 and ArcGIS 9.3 would be very useful.

Best Wishes

Have you looked at ASTER GDEM data?

ASTER GDEM

Unfortunately the quality is varying for some areas, but it may be worth looking at.

Have you looked here:

or here:

If not your options are limited to scanning the paper maps and creating a DEM from the digitized contours. The folks at Eastview or numerous Indian contractors (some of which can probably be found on this site) can help make this tedious task less so for a relatively small cost.
