Help understanding Aspen VOR/DME approach

The plate is here-

http://www.airnav.com/depart?http://.../05889VDGC.PDF

While trying to fly the approach in the sim I flew to the MAP with
relative ease but had trouble getting low enough to make the runway
without getting too hot. Looking at the plate it seems a drop of 2380'
must be made between MAFMU and the runway in a lateral distance of
1.4NM, this is a descent angle of 15 degrees!

Could someone please confirm this or help with my interpretation of
the chart. I am a PP beginning instrument training.

TIA
