Not sure it would make any difference, but all of my cairns are on my course, on my land. Some have a history, I saw something special there, felt something special, marking a turn in a seldom used trail, an uncommon wildflower, etc. Most of them are quartz, colors running the gamut from clear crystal to orange to rose and red. Some delicate and a foot tall, others very large stones and over five feet.... all dry stacked and all eccentrically built.... looking as if gravity forgot it's job. Kinda found art for me. Something to do with my OCD. [emoji106][emoji41]
The first time I saw a rock stack I thought it was sort of cool...unnatural, but cool. Then I started seeing more and more of them and the coolness factor went away.
I went to Mackinaw Island a few years ago and you couldn't look down the beach without seeing rocks stacks literally every 20 feet. I understand that a lot of State and National Parks are the same way. I am firmly in the "leave no trace" camp.
I may alone in my opinion, but I see rock stacks as unnatural eyesores.
