Talk about a trip you took out to Anza Borrego

Stone Tools 2.0

rockhopper Posts: 668 3/12/2016	rockhopper Posts: 668 Hello all, Back to my local hiking spot to take some more photos and photo some more stone tools scattered through out the area as I mentioned in my previous post. Again like before, all were just laying around on the surface, gathered to photo and put back in their resting places. I just wanted to add to the data base for those who are interested. Most are crude stone tools along with some finer made points. Point made from Green Andesite as the obsidian source is far away. Typical chippings found all over "The hill" over looking a ancient native American trail. Some crude scrapers. A perfect wheel/ roller. Some worn scoopers. More odds and ends. Tool for arrow manufacture? Tool for stick and bow fire starter? Blooms in the back country My elusive Bob Cat friend. Cheers edited by rockhopper on 3/12/2016

The dark material is found in cobbles in the stream beds as it does not occur in the local terrain. I know the Ryholite was from lava flows millions of years ago from an area on mainland Mexico when San Diego county ( Pacific plate ) was in alignment with what is now Mexico many miles south. Yes, the lichens are pretty neat. Sitting there a long time.
