Tell me about it. I've been interested in GRASS for years, but never
really got off the ground with it. Mostly for lack of a compelling
reason, but also because the sample dataset that ships with GRASS
(Spearfish) is from BFE and I had no context for WTF I was seeing on
the screen. At least I am familiar with the geography around Mt Hood
and that helped immensely. I am still feeling my way, but making some
progress. I'd be glad to show you what I know.
BTW, there is a bigger one (~2meg) now too, the aptly named:

I added 8 more 7.5-minute quads, now 5 N-S and 4 E-W. You can see
Bonneville Dam in the foreground and all of the Eagle Creek
watershed. Still no blue water though.
