I know that water from a landfill is directed to a place where it is treated. I know that this is just a drainage ditch for stormwater. But what's with the color?
A hill is an unusual thing in Raleigh. These "green hills" are manmade. They cover a huge landfill. The hills are dotted with these valves to control the methane release.
Landfills are more than just trash heaps, (see here).
Usually, Cedar Waxwings come in big flocks around here in the spring and fall. This guy came all by himself and hid out in the bushes before flying off.
Monarch butterflies are endangered, but not on the endangered species list, (go figure). But more and more I'm seeing areas with native plants, especially milkweed. Maybe even without government support we can save these creatures.
