In 1815, Mt Tambora in the Eastern Pacific exploded bringing "The Year Without a Summer" the next year. This cache commemorates a monument that commemorates Rueben Whitten who managed to raise 40 bushels of wheat that year. Corn farmers lost their crop three times to freezes, but Whitten's wheat saved his family and neighbors from starvation. Much more information is at http://WermeNH.com/1816.html and my detailed analysis is at http://WermeNH.com/1816/1816-Weather.html.
The coordinates are for a granite marker in his family's cemetery. Access is through private land, but the owner has granted limited access in return for my promise that geocachers respect the site they visit.
Please park at the Town Hall on Highland St at N 43:41.791, W 071:37.938, 0.4 mi south of the destination. Walk uphill from there. Please don't park near the cemetery as the road is narrow, the plants growing on the edge of the road don't want to be parked on, and the landowner is concerned about parked cars blocking the road.
Only one question for "proper credit:"
1) The typical gravestone is a rectangular block of soapstone, slate, or granite from a quarry. What is odd about this monument?
