| Boulder
in foreground has been identified as rough Orbicular (Poppy) Jasper, part of the Radiolarian Chert family. |
||
|
||
| Normally you would walk right past it without noticing it. | ||
|
|
|
| But if the light is right, its unique coloration becomes obvious. | ||
|
||
| Its smooth surface is a kaleidoscope of colors. | ||
|
|
|
| Its polished appearance is due to its creekbed location. | ||
|
||
| Creekwater has dashed against it for untold decades. | ||
|
|
|
| The force of water effectively prevented closer examination. | ||
|
||
| The richness of its red coloration is due to iron in its composition. | ||
|
||
| Its
creekbed location is northwards "as the crow flies" (or the fault
creeps?) of a larger deposit of Orbicular Jasper in the southern foothills. |
