There's a plan to cover this with wildflowers, and I just heard that it has achieved funding, so I figured I'd take a chance on taking a few "before" photos, even though I didn't know where the planting will take place!
As it turns out, having read the crowdfunder info, this is roughly the "westernmost third" where the wildflower meadow will be planted.
