I talked to Alex D. at AMC via email and he provided the following email in response to the plaque. It sounds like co-operation between us as hikers, the AMC, and the responsible USFS office for the areas where these are found will net good results. At least now and in the future we can make them aware of what is going on and what we find and hopefully prevent it from becoming a more widespread problem.
Here's the email sent to Alex:
Hi Alex,
Me again, sorry the last email was so garbled, you can tell how much time I spend on the computer. Here is a link to a photo of the plaque found on Clay.
Thanks,
Scott Lang

Here's the email in return:
Scott,
You are correct, monuments are not allowed on USFS lands and there is a process
for removal of such unauthorized objects.
For example, a family just donated funds to support the construction of the new
AMC Kinsman Pond Shelter in the Whites. The family that donated the money,
donated it in their father's name and had a plaque made to honor him. That
plaque could not be hung at the Shelter because it is on USFS property. So, the
plaque is hung outside of Lonesome Lake Hut on NH State Park Lands (with
permission from the state), 1.9 miles away from the shelter. So, we (AMC) can
not get around regulations regarding plaques in the forest either.
These should be forwarded over to the Trails Supervisor of the USFS or the
Dispersed Recreation Manager in the USFS for the appropriate district.
I will take care of forwarding this on to the Andro District Trails Folks.
Thanks,
-Alex
