As a young'un in the 1950s, I found many arrowheads, spear heads, tomahawk heads, club heads, etc. About ten years ago I divided my collection of probably 150 items, maybe more, between our two sons. I lived in a rural area and had access to lots of farm land. I would try to go arrowhead hunting immediately after the first rain after a field had been plowed. Really, the arrow-head hunting could be good any time after a plowing and before a planting, but I always tried to do it before disking. Disking was more likely to break arrowheads, especially the larger items such as spear heads, than plowing with say a two-bottom plow. I agree with the posts above about focusing on areas that were logically good for the Indians for hunting, camps, etc. Bottom land near running water, nearby ridges, any level area where there are usually hills. The two best fields for me were about two miles apart, as the crow flies. One was level land 1/4 mile upland from water, the other bottom land near but not directly adjacent to a creek. I found totally different items in those two areas, clearly from two distinct tribes and times. In one area the items I found were roughly made, tended to be large, all of a particular rock that was not flint. In the other area most of what I found was precisely made, almost all from flint.
Then fast forward to 2004 when we bought our current country property. I have found 15 whole or distinct partial arrowheads there, almost all in about a 150 yard stretch in a trail I made in low land near a creek. I disturbed this land only a little with a box scrape. All but one are made of white quartz. I had never before found any arrowheads, etc., made of white quartz. Not surprisingly, there are two concentrations of white quartz rock on this property, both within a few hundred yards of where I found these arrowheads.
