What kind of rock types are common to that area so I can narrow down my search in identifying them? I can't see any crystals in a majority. One that looks like shale has visibile crystals. The largest is either weathered or is porforitic.

Probably pumice, which is foamed up from a volcano. It's a good insulator. Try grinding off a bit of it and sniff. If it's pumice, it'll smell like sulfur. It's sulfurous gases that foam it up.

It looks like pumice. Traces of iron would cause the rust.

....I used to off-road in Baja. Are the rocks round? gray? Broken from spherical rocks. Mine were found to spherical and hollow.
They were adorned with different types of quartz in them. These rocks were identified as, Mexican Geodes. Check it with a rock and mineral collector. a geode is gray w/quartz, and hollow, yet not sometimes perfectly round.
