First time while on a big swing through NM/OK/CO, in May, then again in September for the '02 Highpointers Convention. A really neat legit hill/peak in the flats of the plains.
We saw this on the way back from Guadalupe Peak. Broke out the gazeteer, engaged its location and navigated to it and climbed it. Turned out we got a county highpoint! Nice little spontaneous hike out in the beautiful plains.
