- [Voiceover] We're in the Sacramento Mountains, in New Mexico, and we're looking at what's called "leopard rock." These are microbial carbonates, and you've got a little mound with strata that are onlapping onto the mound. The leopard rock itself is-- encrusting forams, a little bit of algae. Not phylloid algae though. Here's a bulbous head, right here. And, you can see why it's called leopard rock, when you can see the textures in this thing. Okay, they resemble the spots of a leopard. But, it's a community off, basically, microbes encrusting forams-- with some algae. But, the best thing to see-- is how-- beds are onlapping onto this guy, so it's a very good example. Even though this is happening at a very small scale, you would get the same process occurring at a seismic scale.
