This rock is very heavy and very dense compared to other rocks of its size, it was extremely difficult to start breaking it up. Steel doesn?t scratch it, but sand paper does. It has sort of a waxy luster. It?s mostly a light tan color with some darker spots as well these streaks of gray/silver.

This 1st pic is the original specimen. It was ~80lbs(36kg). BD626DE0-0DBA-40F0-9994-55B800D9D173.jpeg It?s been in our front yard for as long as my parents can remember. If it?s any help we live less than a mile from the Clackamas river in Oregon. Near riverside park to be a little more specific.

This 2nd pic is a smaller chunk that I?ve run through my tumbler

Finally this last pic is just another random chunk still laying around my yard. This one you can really see the grayish/silver streaks in it.
 

Welcome John from Texas :wave:

Rock 1 and 3 look fossiliferous imo. Not completely sure of the mineral though. :icon_scratch:

Rock 2 is an agate

Rock 4 is Quartzite

Sorry I should have clarified, but all these pictures are actually from the same rock. The first picture is what it originally looked like before I tried breaking it and cleaning it.

Pic #2 is a small chunk of the rock from pic #1. But it’s been polished with a tumbler.

Pic #3 and pic #4 are also pieces from the rock in pic #1. But I’ve washed the dirt, etc away with a pressure washer.

Hope that clears things up
