The 73% I cite publicly is the top-50 within 50m row (73.7% exact, rounded down).

10m gets noisy because many of these caves were recorded before consumer GPS got accurate. The model isn't really missing them, the dataset just doesn't know exactly where they are.

Other miss sources: bluff-face entries, canopy-shrouded entries, skid trails, agricultural micro-relief. Plus caves destroyed since they were recorded.

Methodology paper in prep.

The topography of California has always fascinated me, specifically the deserts (mostly the Mojave) of the east. Originally, I believed the Eureka Valley wasn't part of Death Valley, but was pleasantly suprised to learn it's simply an isolated park of the park. (1/2)
