Just back from a month in Brazil where, among other things, I was photographing rare giant armadillos (see here ) in the Pantanal. But, as always, I kept my head down, with an eye for interesting rocks - especially since Brazil is one of the most mineral-rich countries on the planet.
Well, not where I was. In fact, most places I visited (Amazon, Pantanal) are flat sedimentary basins with little or no bedrock visible - and frankly not even many rocks. Mud mud and sand, mostly. In fact, the best looking rocks I found were some jasper/chert (not sure which) mixed in with gravels used to line pathways in the Amazon! I have no idea where the gravels came from - no one seemed to know - but some of them exhibited some striking color and pattern.
While I wait to see what the tumbler reveals, I thought I'd show this pebble I found on a Puget Sound beach a few months ago, a handsome, multi-colored rock of unknown provenance and composition. This is the joy, and the frustration of Puget Sound rockhounding: you find a rock like this, and then never see another. It could be from anywhere...
Meanwhile, stay tuned for shots of the Brazilian gravel. If I'm not mistaken, there could be some real winners from that pathway.
