Lake Placid

Posted in Crew events on August 6th, 2010

Well it was a fine weekend with calm water for our boats. About a half dozen points were recovered by a crew of ten. A full write up will follow soon.

Please visit the “Future Recoveries” page for this falls outing information.

Thanks again,

Membership Pins

Well, after a long search for a new supply, we have finally obtained a reliable supplier and have since received a shipment of 100 pins. 

Replacement/additional pins can now be purchased at a cost of $10 per pin by forwarding on a check made payable to the COLVIN CREW for the number of pins so desired, along with a postage paid, return envelope to:

Camp Clerk: Michael Webb

New members will continue to receive their first pin as part of the initial membership fee.

How accurate was Colvin’s work

Posted in Colvin points on November 10th, 2009

I am often asked “how accurate were Colvin’s measurements”.

Well, based on the extremely small sampling that I have personally re-measured, I would say it varies from better than what is typically obtained today to god awful. The better work appears to be that in which Colvin personally performed the observations and the worst appears to be that which was performed in his absence.

A 1995 report entitled “Kinematics and Dynamics of Strain Accumulation in the Adirondacks {USGS 1434-94-G-2473, Final Report by John Beavan, Lamont-Doherty Earth Observatory of Columbia University, Palisades, NY 10964} details the use of Colvin station marks in helping to determine the movement of the Adirondack Mountain range. A resulting un-intended conclusion of their work is found in the report as follows:

“Conclusion: The 1800’s triangulation surveys of the Adirondacks resulted in horizontal station coordinates precise to about 0.5 m (when selecting the best data available to us). The 1940’s survey resulted in precisions of 0.1-0.2 m. The 1995 GPS data gives precisions estimated at 0.01-0.02 m. The accuracies of the earlier surveys, while commendable for their time, are insufficient to detect deformation associated with the uplift of the Adirondacks.”

Under the direction of the Camp Clerk (Mike Webb, L.S.) students from SUNY Ranger School made a return recovery to the “Great Corner” this fall. A detailed write-up can now be downloaded from the “Past Recoveries” page.

Well done Mike,

Lake Tear of the Clouds

Just wanted to say thanks to everyone for another successful recovery. All went well with various points being recovered. The weather could have been better on the summits but at least no serious rain. Check back in a few weeks on the “Past Recoveries” page for a full write up.
