Top of the mountain in the morning ☀️ We finished up marking out a large boundary in Eldred last week.
Lots of blazing resulted in a broken machete!

Our hills are still covered in snow ❄️ but this warm spell is definitely giving us some relief!
We were over in Eldred and Ceres Townships doing a large boundary survey last week. Retraced some original evidence with the help of some previous flagging and tree blazes.

Surveying for the Borough of Kane this week.
⚡️ We found a long lost original pipe buried under a pile of large rocks. A slightly larger pipe nearby was assumed as the corner but did not match deed records well, so we did a little more investigating and bingo! Found the original! We had to dig out around the rock and get a GPS shot through the rock. It’s rewarding to be able to re-establish accurate boundary evidence!
⚡️ This project was located right next to the cemetery with the gravesite of the founders of Kane. Pretty awesome to explore.

This weather can’t keep us down! Our CanAm Defender got a winter upgrade. Perfect for laying out proposed oil wells in the hills!

We’re wrapping up a 30acre boundary near Port Allegany. Talk about steep terrain!! ⛰️
🌲 This one was messy with road location changes, a lot of missing property corners and misleading occupation by neighbors.
🌲 Not anymore! All property corners are in place and all property lines clearly marked and easy to follow.
🌲 Can you spot the well disguised corner pipes in the first few pics? And can you spot the surveyors in the last pic? 🧐

We had a couple extra hands for a boundary and garage layout. Teaching him young!
