that is an odd thing.  there's a picture of the same thing on Denton Doc's trip report page

definintely looks to be a new feature

grafitti ?  seems to be unlikely, as who would go to all the trouble to portage some white paint that far into the park ?

I wonder if it is some kind of survey marker or something of that nature

My belief is that it is graffiti.  ALL the pictos I know of or have seen are rust colored.

To me, that looks like a spray paint type drip on the right. You know what though, I don't recall a specific rule about not spray painting rocks. I'd seriously doubt it's anything but graffiti though.

You wanna leave a semi-perminant mark? Sign your name and make it worth something like these guys did:

Maybe an aiming point for a transit or some other surveying equipment like Mad_Mat suggested. It is only about 400 yards from the portage to Wickstead and would likely be visible from there with magnification. I wonder if the park people are doing any surveying or mapping.

It would be interesting to know if the runs are from when it was made or if they came after the rain on the evening of the 4th. I may have to go back next year and see if it is still there.

Ever see all the handprints on the western most (I forget and am too lazy to pull the picture) Quetico Lake site? While the eastern most site seems to have an artists touch, IMO, that pillowed western site does not. Do you suppose they were all yelling "Neener neener neener! You can't catch us old man" on that one?

Although I agree to some extent, sometimes the difference becomes the ex factors. Expectations, experts and excrement.
