It looks like this map is too large for DOMA. Hmmm.
Mt. Penn is one of the few maps in southeastern Pennsylvania that's actually usable in the summer. The white forest is in fact quite open with high visibility.
But I had a similar feeling to the open parts of the forest in French Creek: "Yeah, I can see far...but what is there to see?" There aren't many distinct features in the area, nor are the contours particularly intricate. Again, this is more difficult for me than areas with detailed contours.
The original plan was to do a corridor. But I decided to do a maze because corridors on many DVOA maps are simply too difficult. The visibility is generally too low and the features aren't distinct enough. I've walked away from each corridor frustrated in my abilities and not feeling that I've benefited from the training.
A maze can offer similar benefits, while still being possible to complete successfully (or mostly successfully as was the case for me today :)
For the nerds out there, it turns out that Mt. Penn is actually part of the same physiographic province as the Hudson Highlands. The province is the New England Uplands section, and Mt. Penn's subprovince is the Reading Prong. But since the southern boundary of the glaciers went through Northern PA, this terrain never received the glacial facelift, leaving many of its hills devoid of detail.
In fact, one of DVOA's most interesting maps straddles the boundary of the glaciers.
