Thanks for all the comments and suggestions. I'm beginning to wonder if it's maybe a type of silicified wood. Southwest ND is abundant in agatized/silicified woods, it's all over the fields and all different colors. Southwest ND is also my favorite place to hunt, one of the most beautiful places on earth. A buddy of mine found a perfect Clovis about 15 miles from where I found this point! He also found a perfect Folsom point, a miniature one, perfect in everyway, but the size of a dime!
