Public Domain Dungeon Map Icons

I've been a bit distracted lately with non-blog stuff, but have some public domain icons for your dungeon map.  These are intentionally rough and gritty:

A door

A trap

A secret door

Stairs

And maybe less generally useful but something I've been looking for for a while, animal tracks:

Bear tracks

Wolf tracks

Mountain Lion, puma, or cougar tracks

And, not an icon, but a canvas to place them all on, public domain graph paper:

Haha, yes I'm laughing at myself, but, again it is more about the gritty, uneven feel I was going for, than just reinventing the wheel.  I've been working on a revision of my Dwarven Outpost Kit dungeon with this as the background and I like it.  I lower the levels on it, first, so it's more grey and unobtrusive, but it gives a more hand-drawn feel to the affair.

That's all for now.  I'll share more as I find them and eventually add all these to the borders and Misc zip file that I have on my public domain art page.
