Walker Ranch is basically the same as the famous Woodward Ranch in West Texas. I have spent well over 50 days on the ranch collecting. The material was literally laying over the ground. I brought back a couple nodules that are the size of cantelopes although most are smaller in the couple inch range. I have not cut hardly any of the better nodules yet and have just been experimenting with the lesser pieces. A fantastic Plume Agate I love this material!
