Here's my first effort at a Lost Lake point. I broke the tang off on the first notch but went ahead and notched the other side and then glued it back on, more or less where it was. I was attempting to copy the lower right point on page 451 in Overstreet, 7th edition. Dimensions are 3 1/4 X 2 1/4 X 1/4. Made from a spall. Obsidian wouldn't be authentic, but it's what I have right now.
Picture above, now. I wonder how I managed to post the pictures without the text.
