Identification: type of sedum?

I saw this plant on a rocky outcrop on the Oyster Dome trail just off the Chuckanut Drive in Washington on Monday. It looks like a type of sedum to me, but I can't identify it. The white flower was small (about 1 cm diameter). There seems to be maybe more than one type of plant in the picture.
Does anybody recognize it?

 

Montia parvifolia, compare against this photo on the WTU Herbarium site.

 

Thanks for the ID. I realize now that I've seen it before.

 

Stone-crops produce differently shaped, starry looking flowers that are not striped.

 

Okay, thanks for the info. I've seen quite a bit of miner's lettuce locally, but I didn't think it could have the type of leaves as in the photos I took.
