The Weekly Photo Challenge: Forces of Nature

1-DSC_6358The weeks photo was taken at the Pinnacle National Park in California.  These crazy looking rock formations are visible all over the park.  I took this shot from the High Peaks Trail on the way to Hawkins Peak.

From the Pinnacles National Park site page:

Pinnacles National Park, located near the San Andreas Fault along the boundary of the Pacific Plate and the North American Plate, is an excellent example of tectonic plate movement. The Pinnacles Rocks are believed to be part of the Neenach Volcano that occurred 23 million years ago near present-day Lancaster, California, some 195 miles (314 km) southeast. The giant San Andreas Fault split the volcano and the Pacific Plate crept north, carrying the Pinnacles. The work of water and wind on these erodible volcanic rocks has formed the unusual rock structures seen today.

A great place to hike, with several challenging trails.  The forces of nature are evident from most of the high trails in the park.  If you are traveling in California, I would strongly encourage you to make a stop at the Pinnacles National Park.

Both of these pictures are taken from the picturesque, but challenging, High Peaks Trail:


Where are you hiking this weekend?

If you’re looking for me, I’m over the hill.

The Thursday Picture – Whole Lotta Shakin’ Goin’ On

San Andreas Fault, Los Trancos OSP, Hike 28Last Sunday I hiked in yet another one of the Peninsula’s Open Space Preserves: Los Trancos OSP.  This preserve is part of the Mid Peninsula Open Space District

What makes this preserve interesting is that the San Andreas fault runs right through the OSP!  In this picture taken on the Fault Trail, the posts with yellow banding are located directly over the San Andreas Fault.  The fault is the dividing line between two tectonic plates.  The American Plate to the left in the picture and the Pacific Plate to the right in the picture.  The Pacific Plate is moving northward at an average of 3/4″ per year.  We’ve had two major earthquakes in the Bay Area that occurred along this fault area.  The 1906 San Francisco quake and the 1989 Loma Prieta quake.

With just over 5 miles of very scenic trails, The Los Trancos Open Space Preserve was a great place to complete my 28th hike of the year!

If things start shaking, and your looking for me, well…I’m over the hill!
