It is new to me.

There are some rocks here that I have never seen, Here are two. Actually as one is a pudding stone so there are more like 8 or 10.
This is a small sample little bigger than my fist however I have seen multi ton boulders.  Could this black rock be weathered ilmenite?

The other is coal black. The shiny places are reflected light. This is coal black.

Yes, AuTe2, you are in a good area to be a rockhound. BC has some very  interesting and unique rocks.
I like the "pudding stones", or conglomerates, too. The contrasts in some are simply beautiful. Great stones to slab and see what a cut surface looks like.
The black rock could be a lot of things. We would need a hardness, a streak color, and weight wouldn't hurt. Also check to see if it is magnetic. A simple way to check for weak magnetism is to lay a compass on a flat surface and pass the rock over it to see if it makes the compass needle move.

The hardness is between 7 and 8 and the streak seems to be the same color, black and a little faint. I do not have a scale or graduated cylinder for a density testJoeM wrote on Jun 17th, 2024 at 11:49pm:

Ilmenite is a good guess. It's just the specimen is so rounded tell tale signs have been smoothed away.
Hematite is not naturally magnetic but some Ilmenite is naturally weakly magnetic. You can try the compass test and if the needle moves it's Ilmenite, or something with Magnetite in the mix.
