Resources – Slide Collection

During the 1970s and 1980s MHS staff members assembled a collection of photographic slides which today number 830 slides stored in a special container. Although the subjects and names assigned to the slides were stored in a spreadsheet, viewing these slide photos was awkward. So in 2023 we scanned all these slides and saved them as high resolution tif files as well as medium resolution jpg files and thumbnails. Because of overlap with the subjects assigned to our other archive collections we have not yet attempted to update slide descriptions and modernize subject terms such as “Indians”. Please be patient. Many of the slide photos were taken during “Romerias”, MHS organized trips to missions, museums and historical sites. They thus include photos of paintings and drawings whose copyright status is for now unknown, and of living individuals who may wish their privacy preserved. Due to the large variety of “subjects” we have developed a system of ten time periods we assign to all our scanned items. This has allowed us to create “time period” based web pages for the Slide Collection which serve as catalogs. These catalogs include a thumbnail image to give a rough idea of what the slide images are about. A similar digitization process is now being undertaken with our collection of physical photo prints. It is our goal to provide a PC at the History Center which visitors can use to browse the collections and request higher resolution images. As we figure out the usage permissions associated with each scanned image we will make, if possible, a web resolution image available online that can be loaded through links in the catalogs. Please refer to our Disclaimer to determine how you may make use of the content on our web site.

Geology & Paleontology Due to the small number of slides covering these periods they have been combined into a single catalog. Geology refers to rocks and land formations that make up Moraga and the surrounding region, what today’s geology is and how it came about, and can include current issues such as landslides and earthquakes. Paleontology refers to prehistoric non-human life in the area (ie mastodons) but can extend into the present to include information about how Moraga’s flora and fauna have changed to its present form.
Native Americans Refers to the pre-European inhabitants from past to present, chosen as an alternative to “Indigenous” to replace the term “Indian” which past archivists used extensively.
Early European Exploration 1500-1774 Refers to European exploration of California prior to local European settlement that began with the de Anza expeditions in 1774.
Spanish Period 1774-1821 Refers to the period of Spanish influence from the de Anza expeditions until Mexico secured independence from Spain.
Mexican Period 1821-1850 Refers to the period of Mexican control until California became part of the United States in 1850. Includes the granting of the Rancho Laguna de los Palos Colorados Land Grant to Joaquin Moraga and Juan Bernal.
California Americanization 1850-1900 Refers to the second half of the 19th century during which ownership of the Moraga land grant fragmented and eventually shifted into the hands of “Americans” such as Horace Carpentier.
Early 20th Century Moraga 1900-1945 Refers to the first half of the 20th century with the end of World War II in 1945 treated as a major turning point in Moraga’s shift from an agribusiness into a suburban bedroom community.
Unincorporated Moraga 1945-1974 Refers to the post-war period until the incorporation of the Town of Moraga in 1974.
Incorporated Moraga 1974-present Refers to the history of Moraga since incorporation in 1974.
