How's the map holding up?

The existing map is sort of ok, if you try to imagine the vegetation and trail situation 20 years ago.

And then a significant portion of the map was new, using LIDAR data from 2016 and having Kartapullatin do its thing. But, since the LIDAR was flown, a lot of that area burned, and some of that area was logged post-burn, so even the vegetation there was wonky. I found the contours up there to be really fascinating, since it was a landslide area from who knows how many centuries (decades? millenia?) ago. The ground was lumpier than standard Teanaway, the reentrants way less distinct; in some places, an entire hillside was kinda marshy as the water was seeping out over a larger area. One of the controls was on a pond on top of a spur, which just makes the head a-splode.

I picked up all of the controls in the LIDAR area, as well as the 4 northwesternmost in Teanaway, and the 4 southernmost in The Tongue. I had to abort my initial attack on one of the Teanaway ones because the green got too thick (mapped as open land with scattered), but the others were ok. There's one trail intersection on the map way out west in Teanaway, and the trail run goes through there. The first time I marked that for the trail run, all 4 trails coming in where about the same. With all of the trail runners going through there, and the other 2 directions not being used at all, that trail intersection is barely noticeable now, to the point where it doesn't need any trail marking for the run.

I love ponds in places like that. Ran into some of that out here recently, except it was swamp instead of pond on top of the hill. Mind-boggling. And we have one of those old landslide areas near our Glacier cabin, and it makes contours do some really strange things.

Jon is a Kartapullatin fan. Nice to hear about the lidar update. Yikes on the vegetation though. So hard to keep that updated. Ah well, here’s hoping we’ll be out that way next time the club has an event there!

I feel like the vegetation isn't that big a deal, since other than the odd green reentrant most everything is somewhere on the vague orangey-whitish spectrum, none of which really restricts passability and not much of which is usable for navigation anyway, so if you generally just disregard vegetation you won't be punished for it.
