 | Just a short distance from our starting point at Summit Overlook we came across this roadcut of the Lower Topanga Formation where we took our group photo. Participants for the May 24 GeoTrek included, left to right, Leni Field, Gene Fritsche, Dayanthie Weeraratne, Jonathan Miller, and Sue Fritsche, who took the picture.
 | Here we are at the Melhorn Overlook from where one can get a good overview of the city of Van Nuys.
 | Morning snack time was approaching as we walked along Mulholland Drive looking at rocks in the roadcuts, and just at the right moment we came upon one of Los Angeles' infamous Taco Trucks. Needless to say, we availed ourselves of the opportunity.
 | Our luck held out and as it came time for a morning nature call we walked by a movie company portable outhouse. We secured permission from the security guard and found that the facilities had clean flushing toilets, wash basins, soap, and paper towels!
 | We came to the halfway point on our hike at the Mulholland Drive bridge crossing of the 405 Freeway just about lunch time.
 | A short ways farther on we found a nice place for lunch on the lawn of the Bel Aire Presbyterian Church. During lunch we had a good view of the valley area around the Sepulveda Flood Control Basin.
 | As we walked along Mulholland Drive we did have to watch for traffic, but the walking surface was firm and flat.
 | This view of the San Fernando Valley looks across Encino toward the runway of the Van Nuys airport.
 | At San Vicente Mountain Park is an abandoned cold-war era NIKE base.
 | This vine that is common in the area bears large, prickly seed pods. It's called a Wild Cucumber.
 | This view from Mulholland Drive northward across the Encino Reservoir shows the Santa Susana Mountains in the background. The north-south street with lots of white buildings along it is Reseda Blvd.
 | Here's a telephoto picture looking down Lindley Avenue of the CSUN campus. On the main campus to the left of Lindley, the Oviatt Library stands out. To the right of Lindley are the campus residence buildings.
 | As we walked along this unpaved portion of Mulholland Drive studying the geology, our emphasis shifted from watching for cars to avoiding speeding bicycles.
 | We finally got high enough along the crest of the mountains to look south and see the Pacific Ocean. In the distance is a large ship and beyond that the Palos Verdes Peninsula.
 | Near the end of the day, Gene took a planned short cut. Unfortunately at the end of the short cut was a steep, slippery downslope.
 | We all made it safely to the Reseda Blvd. trailhead in good shape.
