retaining wall. It is also prettier, and doesn't out-gas that disgusting petroleum stench in the sunlight.
Even when not stacked, but used to retain a 2:1 slope, stone will do a fine job.
I utilized all the gorgeous top soil from the area on the left of this image in four 16 sq. ft. 18" raised planter beds and elsewhere. The dry stacked
local stone holds the change in elevation very well. My SW slope gets a little flatter, and I like the look of the stone with some nice introduced
moss finding a home there too.
