There are many rock walls up here in the mountains, including some that are around my cabin. This one, above, is a tenth of a mile long, reflecting an enormous amount of hard labor to create.
These walls are reminders of how intensely farmed this land was. A remarkable thought considering how rocky and how steep it is up here. Certainly an acknowledgement of the determination of residents of these mountains decades ago.
Many of the rocks in these walls are a bright yellow color. That color is Sulphur Dust Lichen (Chrysothrix chlorina).
One of many lichens that can easily be found up here, growing on rocks, trees, buildings, soil, and tombstones.
