#FindOutFriday Sedimentary rocks are made of minerals that were deposited into the Earth by wind, water, ice, plants, or animals. How can you identify sedimentary rocks? Look for visible layers of different materials that have been compressed together over time by nature's elements. This is an example of colorful layers of sedimentary rock in Makhtesh Ramon, Israel.

Say what you will, you cannot escape the beauty, magnificence, and grandeur of the murals painted on freeway bridge columns in Chicano Park. You are surrounded by the largest collection of outdoor murals in a single public setting in California. Beyond beauty, the park and murals are historically significant for the r...ole they played in the California Chicano Civil Rights Movement. Come hear why and learn why you will want to visit this park where art and the messages communicated in them are as relevant today as they were back in the late 1960s.

Hi. Have a little mystery item for you. This object was found in a historic residential dump area dating from the 1930s to 1950s. It is glass and weighs 10.8 oz. or 305 g. On one side are very precise grooves that look like they were cut it, not from the mould. Any help is appreciated!

What is it? Hint: This species of shell did not become prevalent in San Diego until about 4,000 years ago when the water warmed. #WhatIsItWednesday #Archaeology #guessinggame
