Looking at the camp going all the way to the edge of the river's bank sure make you think about what has gone down stream. My wife and I have been tubing and swimming (before the drought) in that river for many years and never found much. When a sure enough good rain hits that part of the country above Barksdale and Camp Wood, the river can get bank to bank in a hurry, maybe they don't stop tumblin till they get down close to Uvalde! lol
PRECISELY MY THOUGHTS ON THE MATTER
Today's edge of river bed is nothing like where it was as little as 500 yrs ago, so where is the last 9,000 yrs ? ....I always say " the Gulf of Mexico " ( just a little past Uvalde )
The "tumble" factor is obvious from looking at the nature of all the rest of the rock in the present river bed...What may have been a great corner tang
might well be a long thin lump of flint by the time it nears Uvalde...round pea sized by the seaside on the gulf
