It does appear to be some variety of Arabis. Thank you!
The really funny part....my neighbor and I are very close and we are always trading plants. If one of us needs something for a spot we go over to the others with a shovel and pick something out. I needed something to stabilize an small inclined area. She suggested this plant. But what is so funny is that I purchased another type of Arabis a few days before and had it planted near by! Too funny.
