Hal, most of the river points you've seen me post are from one general area. It's about a 3 mile strip on the Columbia and the tides do the dirty work. Very rarely I will see other hunters, I know most of them in this area anyways. My new pictures with kayaks is a new area I will be trying out now that I can get there. It easily tripled the number of producing sites I can hunt. Also you asked about the lack of obsidian flake in the other picture. Obsidian is fairly rare west of the cascades and north of Eugene, it's there but not nearly as prevalent as the jasper and agate materials. The few you have seen me post where from east of the mountains except for one lone point from the Columbia.

Very informative and blending one hobby with another ( boating & flinting ) is a good deal.
Our fossil club used to do kayak expeditions on the Brazos ( thats in Texas )...usually at times of temporary low water flow exposing new sand bars... excellent finds ( bones & teeth )

Best of continued luck to you

Most of the obsidian that is found west of the cascades was brought over on the trade routes. one of the main trade routes goes from the cottage grove area to the Oregon-Nevada border just outside Adel.These were mostly Kalapuya-Paiute routes. Fern ridge resevoir (west of Eugene) is where a very large po****tion of Kalapuyas lived. When the lake goes down in the winter the lake bed is littered with Obsidian flakes.There is also a lot of obsidian in the Coburg Hills just north of Eugene.Otherwise mostly the agate and jasper and some points made from petrified wood (oh how I would like to find one of those!)

Life aint fair....
Few years ago the petrified in Texas subject came up too....I had no full points of the wood so I dumped out every bucket of pieces I had....We're talking M E G A NUMBER OF PIECES....not one single teeny ween little identifiable piece of petrified wood...
and that continues to this writing...I dont have a wooden point.

There WAS a double reason for the bucket search....while the goods were spread out, I killed the lights and hit them with a U/V light. Nothing....glowing points must be mainly farther west ( NM AZ NV ? )

Heading for the Starr ranch dig this morn....maybe some hard wood find

hal: the best locations i have found wood points:
n texas ---sulphur river
sabine rive
s texas ---lower nueces river choke canyon to corpus

Tks Angus, We'll take special note of the way you have phrased your input.....
PW can probably be found in almost any drainages all over TX....But the thing for our artifact hunting is: was the quality good enough to flake AND was better quality chert / flint in low supply that would force them to use PW ?

Thats a very historical "diggers handle" you have chosen for postings...
Many many years ago there was a very old veteran texas digger of that name ( sort of the George Washington of flint )
Last we heard of him he had given up digging in favor of hand sewing quilts that kept him in his rocking chair at the rest home ...

hal : i have now given up sewing quilts and gone back to flint hunting
i'm going to keep the rocking chair !

We suspected that that was you...to heck with quilting !
