[Tom Rankin]

A: Apparently not

If you can't see the picture, there is a new Benchmark that says in the outer circle:

'USDA Forest Service & NH Land Surveyors Assoc'

And inside,

'Mt Tecumseh 3997 Ft. 2019'

Add the moose poop and round off and there you go, an excuse to "count" it.

I guess its time to build a 3' cairn

Whoever maintains that trail has it on their to-do list, I'm sure. Dude loves rock work.

This has been discussed to death. It's still an official 4,000 footer and remains on the list. The 4K committee has made no decision either way on it. The elevation on the new benchmark is also incorrect.

Maybe it is tied to sea level

According to the LIDAR survey, which hasn't been made public yet. However, the revised elevation for Tecumseh has been published elsewhere.

The LIDAR data has been public since at least June.

Larry Garland has Tecumseh at 3995 using the new data. The same data the USGS is using. ::shrug::

Can you provide a link to where the data has been made public? In working with him, it's my understanding that hasn't happened yet.

Question: Does LIDAR penetrate to ground level or actually measure forest canopy level?

[kltilton]

The elevation on the disk is based on a GPS survey by the Young Surveyors Group of the NH Land Surveyors Assoc. back in June. A report and/or article will be published soon. The GPS survey is more accurate than the LiDAR data for this particular spot.

It can/does do both, called "last return" or "first return."
