>>21778962no, all the mines in my geographic area are clay mines. We have brick houses and brick sidewalks and brick roads that are 100 years old and outlive structures made of anything else. The reason towns where i live even exist are built upon clay mining operations. I won't find some 'hidden treasure' other than the experience itself
i spent 30 minutes digging a tiny trench to let the water flow out to be the first one in a long while to enter is treasure enough for me
