By the time I received the call, the project personnel that had contacted BCR were thinking that it could be a fossil, or maybe it could be more recent bone. It was now my job to drive from Barstow, where I had just finished another small project, to the Rosamond site so I could assess what the material in question was and whether anything further needed to be done. https://images.squarespace-cdn.com/content/v1/6738f7731a52d458f9986e06/8a6a1fe6-dbb0-46fa-930b-86c8dd4f710f/mastadon-units.jpg Bridging the Past with the Present - 16,000 Year Old Columbian Mammoth Discovery & Recovery - Make it stand out The three archaeological excavation units. https://images.squarespace-cdn.com/content/v1/6738f7731a52d458f9986e06/c4a468d2-342d-4b3f-83f8-1286f7363688/mastadon-grid.jpg Bridging the Past with the Present - 16,000 Year Old Columbian Mammoth Discovery & Recovery - Illustration of the grid that was set up over the entire area The archaeological excavation units are shown in gray, and the bones are sketched as well.

Absolute dating refers to methods which provide a numerical date range (e.g., radiocarbon dating, optically stimulated luminescence). Relative dating refers to methods which place archaeological material into sequences, showing which artifacts/sites are older, coeval, or younger when compared to others (e.g., stratigraphic sequencing). It is typological segregation, a relative dating method, which allows archaeologists to quickly determine the date range that a particular projectile point is associated with. This method involves sorting artifacts into distinct categories or “types” based usually on their overall shape. Types are particular to geographic regions and thousands of types have been developed for projectile points around the world. https://images.squarespace-cdn.com/content/v1/6738f7731a52d458f9986e06/e105a3fe-fa9d-455b-a73d-c998533a5115/bcr-artifact-arrowhead.jpg Bridging the Past with the Present - How Archaeologists Know the Age of Artifacts - Arrowheads & Typologies - Let’s look at an example. BCR Consulting archaeologists found a projectile point during a survey of a project located in the western Mojave Desert between Barstow and Needles, California (see photo). The point had several distinct shape qualities which were most helpful in assigning it to a type. It had a stem which was wide and square with a concave base which was thinned near the end of the manufacturing process. The blade was excurvate (rounded outward). Based on these things and the overall shape, the point most closely matches the Stanislaus Broad Stem type, which is part of the Borax Lake Cluster. It’s date range spans from 6,700 to 6,200 years ago. https://images.squarespace-cdn.com/content/v1/6738f7731a52d458f9986e06/543b1d0f-0256-47b9-a345-eaf7434ae264/arrowheads-stanislaus-broad-stem-type.jpg Bridging the Past with the Present - How Archaeologists Know the Age of Artifacts - Arrowheads & Typologies - Stanislaus Broad Stem Arrowheads Pictured here are two examples (taken from Justice 2002) of Stanislaus Broad Stem points which closely match the example discussed above. https://www.bcrcllc.com/articles/prehistoric-ceramics monthly 0.5 2025-11-06 https://images.squarespace-cdn.com/content/v1/6738f7731a52d458f9986e06/ebb015cc-f916-45c9-956a-8f8be7170a92/prehistoric-ceramic-analysis_coiling-pottery.jpg Bridging the Past with the Present - Prehistoric Ceramics - Make it stand out Coiling Pottery (Ancient Pottery 2025) https://images.squarespace-cdn.com/content/v1/6738f7731a52d458f9986e06/8c52732a-5c10-4cf4-93a7-132cd1004b79/prehistoric-ceramic-analysis_cahuilla-ceramic-vessel.jpg Bridging the Past with the Present - Prehistoric Ceramics - Cahuilla Ceramic Vessel (Native American Net Roots 2019) Figure 1 Figure 1.

Although the median and much of its original landscaping remain in place, the line was completely removed sometime in the early to mid-twentieth century. People have told me about sections of track that are still there, but I’ve never seen them.
