HiPOD: Channels in Rahway Valles This suggestion footprint contains channels and ridges that may have been created by volcanic, fluvial, and/or glacial processes. Higher resolution observations could help to untangle the histories of volcanism and water in this region. uahirise.org/hipod/ESP_07...

Image shows flat terrain with a very thin channel (or ridge) extending from the top right to the bottom center, where an impact crater also appears.

HiPOD: Light on Dark This stunning image shows bright exposed bedrock that might be hydrated, sulfate-rich terrain. This makes the scene one of mineralogic interest earlier identified by the CRISM instrument on MRO. uahirise.org/hipod/ESP_076941_1505 #Mars #science #NASA

Enhanced color closeup shows large outcrops of bright bedrock with dark patches of material throughout the scene. Some of the outcrops have small mounds.

Interesting rock photographed by the Mars Perseverance Rover yestersol (Sol 1841). White balanced color. flic.kr/p/2s9wWuJ

A rock with an interesting mix of colors and textures. Surrounded by gravel with the gravel a little more, um, gravelly, to the immediate right of the rock. Below the rock, the image is obscured by out-of-focus rover parts.

#fossilfriday After 20 years, I finally found clam geodes in the Purisima Formation in Santa Cruz, CA! These are ~5 myo Clinocardium (cockle) shells that were incompletely filled in by sediment after death. Groundwater rich in dissolved calcium carbonate then precipitated calcite crystals.

The part and counterpart of a clam geode. The mouth of the clam is pointed down and there is a wedge of cemented sandstone at the bottom; the upper 2/3 of the clam is infilled with incredible amber colored dogtooth spar calcite, about 6-8 mm thick.

Image cutout shows a pedestal crater on the surface of Mars. The ejecta blanket from the original impact is still visible around the crater, because it was more resistant to erosion than the surrounding terrain.

An image of a rock thin section viewed under the microscope in cross polarised light. The sample is dominated by large olivine and clinopyroxene crystals which are exhibiting bright second order interference colours. They are set in a much finer groundmass which contains abundant plagioclase crystals, recognisable through their first order grey interference colours and long, thin crystal shapes. Large vesicles are scattered through the sample, appearing rounded and black.
