The original Woodward Ranch is well-known for many decades for its black and red plume agates as well as other types of agates found there. Even today, the agates are still being found with patient searching and digging and it helps that the adjacent Walker Ranch, once part of Woodward Ranch, is open to arranged collecting tours. The agates found there are generally gray, black, red, pink and yellow, and white, often with black and red plumes, pseudomorphs and sagenite inclusions. There are a lot of brown Moss agates around but they tend to be ignored or discarded.   I had explored the geology of the ranches and it was interesting to note that the agates are found in clusters in least three distinct basalt beds. Anywhere else along the same beds are hollow cavities with very little stuff in them. It's possible to find free-standing agate-encrusted plume structures in some of those hollow cavities. The green basalt bed at the bottom, produces white agates, the middle reddish-hued gray basalt is the source of plume agates while the topmost bed tend to contain quartz geodes that sometimes have amethyst in them.

Rough Appearance: Brown "Biscuit-like" to domed/cone-like forms, sometimes showing bits of agates, also in grape-like forms (plumes)
Mostly quartz with black plumes covered with thin agates. Some come with brown "mud" fragments at the bottom.
Solid agate with black to red plumes are characteristic while solid & colorful banded agates are quite rare.
Brown to yellow moss inclusions are widespread.
The agates from both Woodward and Walker Ranches share the same source, cannot be distinguished.
