Figure 1. Map of the northern portion of the Southern California Bight and the Channel Islands archipelago showing both the sourthern and northern groups. White boundary around the Northern Channel Islands is the 70 m isobath showing the general extent of Santarosae and the adjacent mainland ~13,000 years ago.

Dr. Jillian Maloney, Luke Johnson (alumni 2020) and collaborators, published a paper in Frontiers this month. Their work adds to our knowledge of the long-term ecology of Santarosae (superisland during lower sea level, composed of todays San Miguel, Santa Rosa, Santa Cruz, and Anacapa Islands) and how the landscape evolved since the late Pleistocence. They also located areas that would have been of interest to hunter-gatherer early maritime peoples.

Luke Johnson presented this work to the Department in May of 2020. To read Luke’s abstract and watch his defense click this text.
