A friend and I were walking though a forest in western Massachusetts. We came across a large boulder. As I walked past, I placed a hand on it and noticed it slightly shift. The boulder was evenly balanced on a smaller rock allowing it to move several inches. Although it only moved a small amount, the effect was amplified by its size (6 feet high) and obvious weight. We acknowledged our finding, recorded some video and moved on.
The encounter with the boulder is good example of how I work. I gather material and information on a daily basis. I am intuitively searching. I wouldn’t have realized that the boulder moved unless I bumped into it and the movement would have been left in the forest unless I recorded it.
