The good: It’s a bedded sandstone, rust-red strata alternating with finer-grained, brown and buff ones.
The bad: The main “cross-bed” in my sample is actually a small reverse fault. There is one part of the specimen, maybe 1”x .5” (on an 8”x 5” slab), that displays cross-bedding, but it is very difficult to see on account of the fault being more obvious. Also, the title doesn’t lie: You’re paying for a slab of sandstone that was cut, washed, and lacquered. The display side is shiny, but pitted (it is a sandstone, after all), and the resultant, chaotic luster detracts from the overall utility of the specimen.
