verified this on Winprom. However, the probability that it actually

does take the state prom is very low. The 2780' contour on the summit

is very small:

Along the lines of the Chimborazo vs. Huascaran debate and the Pico

Colon vs. Pico Bolivar (Colombia) debate, we have the age-old debate

of what is the Pennsylvania state prominence point :-)

I visited Wills Mtn on Dec 20. Deer season is over but the gates were

still open to within about 2 miles of the summit. On the way there I

searched for BM 1924 and BM 2609 (very near where the road ends) so I

could calibrate my Garmin GPS+altimeter, but no luck. BM 1924 is

apparently underneath a small parking area along the road, and BM 2609

is covered with fallen trees, so I couldn't find either. There was

minimal snow on the ground.

Upon arriving at the summit area, I used my GPS to walk where the 2780

contour is supposed to be. As noted before, the contour is very

small, and I don't think there could even be 10 feet of gain, probably

much less. Since Wills would have to be 2799' or so to really contend

for the PA prominence point, I think we can safely rule it out,

whether you accept the natural or the man-made saddle.

It is too bad, since Wills is the highest of the 3 contenders and

feels like a mountain; unlike Shade Mtn, which at 2180'+ feels like a

hill.

I also took the opportunity to visit Martin Hill (inter prom 1405',

elevation 2775'), probably the 4th largest prominence in PA. I

started at the Blankley Picnic Area (apparently the dirt road is open

year round, though not plowed) and hiked the Cabin Trail to the

ridgeline, then took a forest road to the summit. Easy hike.
