My granddaughter is here ahead of cousin camp and we took her to the local museum (Sterling, Colorado) I was browsing their gift shop and found a brand new “old stock” Jen Taylor hardback book in near perfect condition. If it were not for the price tag(which i removed) it would be perfect. I’ve had several people ask me for a copy and so I’m putting this one out there since I have my 2 used copies. Price is $400 firm which is still a pretty good deal considering I’ve seen them going for twice that amount. If interested, PM me and I’ll tell you how to pay. 1 book only. First come….

We just added the "Big Red" Clovis cast from the Fenn Cache to our website. Although this has been cast before, I think Myra did a particularly good job of capturing the subtle color changes in this piece. The original is made of Big Horn Chert. It's now available through our website. mammothruncasting.com Thanks for looking.

I have two copies of the original printing of my book on South Platte River artifacts remaining. I'll do a second print, but they won't be numbered. Also, have one Jeb Taylor, Projectile Points of the High Plains (Spiral Bound) along with a few copies of Stone Fruit, Never A Walk Too Far, Mostly Sand and Gravel, and Goff Creek, the Bill Macormic Collection. These would make excellent Christmas gifts for your favorite artifact friends. Available through mammothruncasting.com With the purchase of a book, you will receive an artifact cast from the High Plains as a bonus. You will receive one cast per book purchased through December 21.

Thanks for your patronage over the past few years. We have sold thousands of books and thousands of casts, and we appreciate each and every sale!

Wishing you all a very Merry Christmas and a Happy and productive New Year.
