Wild Roses Along the Racecourse. It’s that time of year again, when the wild roses bloom along the Racecourse. Their fragrance beats domesticated roses hands down.
Wild roses, at the County Line take-out.
The apache plume are also blooming, and the canyon grape is leafing out. The flow is 1200 cfs, and will very likely continue to rise. Here’s another photo, that is a real puzzler.
This is a basalt boulder that is found along Hwy 68. within a quarter-mile of the County Line take-out. See discussion that follows.
This boulder consists of separate, individual, lava flows. Here, the boulder sits in such a way that the oldest flow layer seen in the boulder faces up (the layer to the left). The individual flows incorporated into the boulder include one whose upper surface is decorated with a swirl pattern, which pattern was created as the lava slowed down and eddied, before hardening. This patterned surface acted as a mold, when it was covered by a subsequent flow. The lowermost surface of that overlying flow is a cast from that mold. The reddish rock surface, in the center, is the cast of the flow pattern found on the surface of the older flow (hidden from view).
