Summer Snow

Scanning a pit instead of a pile

Landon and I once again drove up to Craftsbury on a bright summertime Saturday. A bike race was finishing up at Craftsbury and we wound our way around bikes and food to set up the LiDAR at our first site. After graciously thanking bikers for not passing in front of the laser, we completed three scans successfully. I’m grateful for the 12-volt battery that powers the LiDAR, courtesy of Craftsbury and we had no problems apart from a dysfunctional connection with the camera – no colored scans this time.

The Japanese beetles were out in full-force at the lower pile. Aside from the occasional bug, the LiDAR scanned and saved the data without problems. The large pit that had begun to grow in early April has maintained its outward expanse and now the entire eastern side of the pile is now completely caved-in.

Data processed without struggle and, despite the bursts of high humidity and temperature, melt appears steady. Will we be able to see lag-time in response to these extreme summer conditions?

The CHIP site and POND site volumes displayed. The break is where a scan would not process correctly. They’re melting quickly!

Temperature sensors revealed!

Summer Surveying with Landon

Today UVM Geology major Landon Williams and I completed surveys of the two piles at Craftsbury. Hot, sunny, and windy helped keep the bugs down while we set up LiDAR around the quickly-melting piles. This scan is the second taken after the upper CHIP pile was disrupted and I’m interested in the added effects of the same amount of wood chips on a significantly smaller pile. Will it slow melt?

No major technical issues aside from the slowly dying 6-year-old Dell laptop, however once we set out to process the scans, the upper pile’s scan proved challenging. The lower pile’s scan processed without problems and it’s melting trend matches previous scans’ melt rate.

Landon’s learning both LiDAR and patience as he works with our old Dell laptop

Opening a pile and spreading snow

Posted: July 12th, 2018 by snowstor

On a really hot day, in the middle of a record breaking heatwave, Lucas got out the excavator and opened up the upper snow pile, removing the chips and a sheet of plastic that seemed to have been causing lots of trouble with the snow and the chips (sliding chips, a large fissure).  With lots of help from others, 6 truckloads of snow made their way to the Village so people could enjoy a bit of sledding and skiing on the night before the 4th of July.  You can read more, hear more, and see more on our publicity page: http://www.uvm.edu/~snowstor/?Page=publicity.html

The upper snow pile and the excavator – it’s melting! That’s Hannah being interviewed for VPR radio story.
