Arrows

My better half went to Texas last week, and returned with a few samples of chert and pictures of Indian arrowheads (and a picture of a stone axe head). It occurred to me that making the spear points must have taken hours, and the arrowheads couldn't have been trivial to make either. But it only takes a second, and a slight gust of wind, to lose it.

After a while I suppose you'd get used to spotting arrows in the underbrush, but I wonder if they were painted to make them easier to find? Later Indians had personal and tribal markings on theirs.
