#FindOutFriday A MANO is a hand-held stone tool used for grinding materials like food, medicine, or dyes on a metate.

Archaeologists identified the site where this mano fragment was found as primarily a Late Period habitation site occupied circa 3,000 - 2,400 years ago.

#FindOutFriday Vessels used for water storage can last as cooling mechanisms for about two years. At that point, salts begin to pe*****te the clay, and they no longer efficiently cool the water.

When ceramic vessels break or no longer work as intended, they can often be used for another purpose.

The Sinking of USS THRESHER (SSN 593): An Update from the Declassified Report

#ICYMI - Did you miss last week's Living Room Lecture? Or would you like to watch it again? You can find The Sinking of USS THRESHER: An Update from the Declassified Report and other Living Room Lectures on our YouTube channel.

Fifty-eight years ago, USS THRESHER (SSN 593), the most advanced nuclear submarine of its time, imploded at a depth of 2,400 feet, claiming 129 lives. After disputing the Navy’s official report about this event, Capt. Jim Bryant filed a lawsuit that succeeded in forcing the release of over 1,700 pages of testimony and 100 exhibits of redacted and declassified material.

Lecture from 8/5/21 by Capt. Jim Bryant and Stephen Walsh: Captain Jim Bryant, USN (Ret.), a former commanding officer of a THRESHER Class nuclear powered s...

#FindOutFriday Archaeologists look at the different rock types and use them as a chronological indicator of when stone tools were made, making them very important during the analysis of a site.

Fine-grained Santiago Peak Volcanics are from the San Dieguito Complex (10,500-7,200 years ago); coarse-grained cobble volcanics and quartzites are from the Early Archaic/La Jollan Tradition (7,200-4,000 years ago); quartz, chert, and obsidian are from the Late Archaic/La Jollan Tradition (4,000-1,300 years ago); and a 15% increase in quartz occurred during the Late Prehistoric Tradition (1,300-1000 years ago).

As promised, Part 2. Today is the Reopening under new ownership. El Carrito quickly became a social hub for Barrio Logan. Although it eventually passed out of Johnston family ownership, it continued to operate as a Mexican restaurant, then called El Nuevo Carrito, until closure in 2016. The retiring owners sought a new owner who would appreciate the history of El Carrito and Barrio Logan: enter Milo Lorenzana, owner of the Por Vida coffee shop on same block. Lorenzana is restoring El Carrito, which will reopen serving breakfast and lunch on June 1, 2018. He has done extensive woodwork while keeping as much of the historic material as possible, even when impractical, and adopting the cream and sage paint scheme of the 1930s and 1940s trolleys. El Carrito Cocina Mexicana is located at 2154 Logan Avenue in Barrio Logan, one block from Chicano Park and a couple of doors down from Lorenzana’s Por Vida Café. In keeping with El Carrito’s history as a community hub, Lorenzana and the adjacent San Diego Vintage Co. host a monthly flea market in the adjacent lot, offering clothing, craft stalls, and local food trucks. Find more info at https://www.facebook.com/elcarritobarriologan/, https://www.porvidacollective.com/, and https://www.facebook.com/barriologanfleamarket/. Figure 2. El Carrito prior to reopening, May 2018.
San Diego Electric Railway Car 150 – “El Carrito” Part 1 The San Diego Electric Railway, in service from 1891 to 1947, was responsible for the growth of several San Diego neighborhoods including North Park and Normal Heights and delivered many of the 3.7 million visitors to the 1915-16 Panama-California Exposition, San Diego’s World’s Fair in Balboa Park. When the system was shut down in favor of buses, many of the old streetcars were demolished or sold for scrap. However, a few of the cars were sold and converted to back-country cabins or suburban cottages in an early example of adaptive reuse. Alfonso “Pelón” Johnston, a Barrio Logan community organizer and musician, purchased one of these streetcars. Car 150 was a Class 2 “Expo” electric trolley car built in 1914 by the McGuire-Cummings Manufacturing Company of Paris, Illinois. The car seated 52 passengers, was mainly constructed of wood, and provided all the latest technology including electric lighting, window shades, and pull cords for signaling stops. Johnston installed the decommissioned car in the front yard of 2154 Logan Avenue, right along the No. 12 – Logan Heights trolley line. He built a stucco enclosure on one end, installed kitchen equipment, and opened a restaurant called El Carrito (“the little car”) in 1948. Written by Senior Historian and Archaeologist Doug Mengers Figure 1. El Carrito under construction in 1947; Alfonso “Pelón” Johnston at right (Pacific Southwest Railway Museum).
