Are there any maps around Spokane? Does EWOC still exist?
Are there any maps around Spokane?
Several. The most famous is Fishtrap Lake, which always seems to be on the shortlist of best orienteering venues in the US. It's about an hour outside of Spokane. The 2010 US S/M/L long champs were in Washington, with the Long being at Fishtrap and the Sprint being at Camp Sekani, a crazy area dense with boulders.
Manito Park is another great non-urban sprint venue, and Riverside Park is generally nice. That's about all I'm familiar with.
There's some terrain that's even better than Fishtrap, and it even has LIDAR coverage. It's the same scabland terrain, but covered in white woods and small ponds. Unfortunately, it's at Turnbull Wildlife Refuge, and there's no off-trail access for anyone.
But to Will's point, just looking at maps and satellites, there's a lot of great stuff out there. Interesting, runnable, and not too steep.
Does EWOC still exist?
Yes, and it'll be interesting to see for how much longer. In late June, they hosted a two-day event: Fishtrap on Saturday, Riverside on Sunday. At the Fishtrap event, there were just two EWOC starts, and at Riverside, it was a little more, but not much. Seattle accounted for 78% of the weekend's starts (and it's a 5-hour drive). Heck, even Vancouver had more!
The club doesn't appear to be that big, and several of the heavy lifters are over 65. For a club like this, they seem pretty open to new things. In addition to Vampire-O, they've also had events like Weird-O, Poker-O, and I think a Hunger Games themed event once. But I don't really know more than that.
There's a long line of Washington orienteering clubs that are gone: Chuckanut (Bellingham), Nisqually (Tacoma), Ellensburg (Ellensburg), Sacajawea (Tri-Cities), and Sammamish (Bellevue).
I've been on most all of EWOC's maps and there are several other nice ones (Liberty Lake, Camp Sekani, Farragut SP), but there's also a wealth of unmapped pine forest terrain, like, all over the place. Unfortunately, they just don't have the resources for new maps, or to update suitable ones to ISSOM. For example, Riverfront Park, Spokane Falls CC, (currently unmapped), Lincoln Park, and Mirabeau Park (currently ISOM) would also be great sprint venues.
