Logging Requirements:
How many Distinct columns are there from the Viewing location?
Estimating the height from the bottom below the lower tree crown line, to the top at the second plateau how tall are they?
Please take you picture with the Columns behind you to block them from view but allow the smaller jutting basaltic columns outside the park to the left across the street to be in your view. Please adhere to this requirement as the picture of the main columns would reveal too much information.
Please do not post your answers in your logs. Please send your answers to the earthcache owner via geocaching.com with the title of the Earthcache and GC number. If you log the cache without sending the completed logging requirement, you will be contacted to do so, and if not sent within a reasonable amount of time 1-2 weeks, you logs will be subject to deletion.
Geology:
Basalt columns are natural rock, magnificent as they are, are a result of cooling down and shrinking of molten rock material, lava, on the earth's surface millions of years ago. It is suggested they obey and have crystalline characteristics. They can form to be hexagonal and can be straight or have an S-Curve shapes. Un-weathered basalt is black, but after thousands of years of weathering, many more beautiful colors evolve. Various lengths and sizes are evident in the Rockville Park, and are some of the largest in Northern California.
Local Information and History:
Speaking with the Ranger staff, these are named after a local residence that borders the park, and has been a care taker and Park advocate for many years. They are simple referred to as "The Tilly's". The formations have several terrace like plateaus and are home to some very large trees, an lots of other plants and insect life.
