Quarry Mtn, Routt County

[Jeremy Hakes]

So... while traversing this entire mountain ridgeline, we found a few things.

1 - The shown HP at the east end of 8252' I believe should be the listed elevation, as it is a hard elevation (not an interpolation).

2 - The BM shown is Agate BM - 8242', which works for the closed contour shown, but is clearly lower than 8252. (we did find the BM).

3 - Backsighting is not possible on these treed summits. At all.

4 - At the west end, where LOJ shows the interpolated HP, I believe this should be either deleted and changed to the 8252' or changed and added as a separate named feature - some maps show this as Air Cone Pt (as there is a FAA Air Cone - no trespassing, death imminent, etc). See below.

5 - The locals, the City of S.S., and some maps refer to this peak as "Emerald Mountain", displaying a dislike of the large quarry that used to be used on the SE slopes of the peak.

I'll add Emerald Mountain and Air Cone Point as alternate names.

Hard elevations that are lower than interpolation of another closed contour do not supersede interpolation unless proof exists that the hard elevation is the HP (leveling). Two things work against the 8252 elevation as a HP in terms of probability:
1) The contour containing 8252 is smaller than the west end
2) 8252 has only a 30% chance of exceeding elevation of an area containing an unmarked closed contour of 8240+ (40' contour interval):

Interesting...I was going to hike Quarry last summer while staying in Steamboat for a week, never got around to it.

But who cares where the HP is, what's the "Lane of Pain"?

Maybe we should think up a 30+mile traverse ending near this area to give the name some added meaning

My internal Gyro said the 8260 was higher.

FWIW, the GPS said it was higher, too. Additionally, from what I could tell, the listed elevation I believe has been mechanically levelled, and is now lower.
