L pointed out that I neglected to include a photo of the thumb scraper that she had found at Roundrock, so here it is:
This was one of those odd and interesting stones that we often come across in our ramblings that may end up in our pockets to be examined later. L can’t recall exactly where she picked up this treasure, though I suspect it would have been in the dry part of the lakebed.
Curiously, this may have been a tool used by a lefty. The smooth area where a thumb rests so nicely suggests the southpaw connection. Here is a picture of your’s truly giving it a fit:
Some online research I have done indicated that the two larger implements we have found may not be scrapers but gougers. Okay. I’ll take that. Thus, here is our collection to date:
On one post-rainy visit to Roundrock, I came across a small pile of chipped stone in an area of washed-over dirt. It may have been a knapping spot — this was in the valley — but when we returned on a later visit, I couldn’t find the chips again. It is ironic that two of my ambitions seem to be in conflict. I would love to find an arrowhead — an unmistakable bit of human-worked stone — and I would love to have a lake. The place where I seem most likely to find the former is in the place where I am trying to hard to establish the latter.
