Tule Springs Fossil Beds National Monument –

What the rocks tell us about ecosystem response to past climate change

with Kathleen Springer, Geologist – U.S. Geological Survey (USGS)

Paleowetland deposits comprise the entirety of Tule Springs Fossil Beds National Monument and entomb the spectacular namesake Pleistocene faunal assemblage.  Study of these deposits in detail, reveals that the very springs that were the magnet and water source for animals in an otherwise arid environment, were highly sensitive to past abrupt climate change. This presentation will show that entire ecosystems collapsed repeatedly in response to prolonged drought. How did the animals respond?  How will modern desert wetlands respond to current warming climes’?

Kathleen Springer Biography

I study geologic deposits associated with desert wetlands, pluvial lakes, and anything else I can get my hands on to query the paleoclimate record of the American Southwest. I was trained as a geologist and paleontologist, with B.S. and M.S. degrees in Geological Sciences from the University of California, Riverside, and spent the first part of my career at the San Bernardino County Museum where I was the Senior Curator of Geological Sciences. Now with the USGS, my research focuses on deciphering paleo-depositional environments of Quaternary localities (paleowetlands and pluvial lakes) throughout the Mojave Desert and southern Great Basin, stressing the application of detailed stratigraphic and chronologic controls. I also use detailed geologic mapping to understand how hydrologic systems in the desert responded to past episodes of climate change and tectonic activity. In addition, I am a lifelong geoscience educator and communicator, specializing in earthquake science messaging by raising awareness of earthquake hazards and risk and promoting natural disaster preparedness, work which continues today.

Brown Bag Lunch Lecture – February 16, 2017

The Archaeology of the Yucca Valley Region

by Daniel McCarthy

Native Americans have lived in this region for thousands of years prior to the arrival of Europeans.  The artifacts or material culture they left behind can tell a story of Who, When, Where and How they successfully lived off the land.  Occupation and camp sites abound along with food gathering areas.  Join us in learning more as we discover our past.

Brown Bag Lunch Lecture – December 15, 2016

A Race Against Time:  Documenting the Conservation Needs of Rock Art Sites

Jeremy B. Freeman, Mary Oster, and Jason Theuer

Bring your lunch, bring your friends, or just bring yourself to our Brown Bag Lunch Lecture Series once a month.  Speakers will present topics of special interest for high desert residents. The lectures start at 12:00 p.m. Admission is $ 5 – Free for Members/Sponsors – beverages will be served.

Rock art sites are affected by a variety of transformational processes that affect site preservation and integrity.  Each site is subject to a unique combination of natural and anthropogenically induced agents that collectively act to degrade rock art figures and their supports.  Although the literature is replete with discussions on the processes leading to the deterioration of rock art, few systematic longitudinal studies have been conducted to document these processes and their role in diachronic changes to panels.  Subtle changes often go unnoticed and intervention is often relegated to reactionary responses to sudden and obvious signs of deterioration.  Conservation management plans provide a means of evaluating the conservation needs of sites and help implement a strategy to conserve the resource.  In this study we are using a variety of methods to collect data at rock art sites within Joshua Tree National Park to understand the agents leading to the deterioration of the rock art.  This data will provide a better understanding of the conservation needs of each site and enable the park to prepare a management plan to help conserve these resources.

Jeremy Freeman and Mary Oster Bios

Jeremy conducted his undergraduate studies in anthropology at Heidelberg College and his graduate studies anthropology at Ball State University.  He has worked as a professional archaeologist for 17 years for cultural resource management firms, museums, universities, federal agencies, and non-profit research institutes throughout the U.S.   He is currently working for the Great Basin Institute which is a partner organization with Joshua Tree National Park where he works in the resources division.  His research interests include:  rock art documentation and conservation management, indigenous cosmological constructs, and mythology and the sacred landscape.

Mary received her B.A. in Anthropology from the University of California, Santa Cruz.  She has been employed as a field archaeologist and researcher for six years, focusing primarily on the Great Basin physiographic region.  She has worked on projects in Nevada, Wyoming, Utah, Arizona, and throughout the state of California; at four National Parks: Joshua Tree NP, Bryce Canyon NP, Lassen Volcanic NP, and Lava Beds NM; and has published a volume in the Intermountain Region Cultural Resources series though the NPS.  Her broad research interests are in geomorphology/geology, landscape archaeology, paleoenvironmental reconstruction, archaeobotany, and of course, rock art.

The status of the Joshua Tree at Joshua Tree National Park

with Neil Frakes, Division of Resource Management at Joshua Tree National Park

Bring your lunch, bring your friends, or just bring yourself to our Brown Bag Lunch Lecture Series once a month.  Speakers will present topics of special interest for high desert residents. The lectures start at 12:00 p.m. Admission is $ 5 – Free for Members/Sponsors – beverages will be served.

There is growing concern among the scientific community that Joshua trees are vulnerable to climate change. Predictive modelling efforts have shown that Joshua trees could be extirpated from Joshua Tree National Park within 80 years or reduced to approximately 10 percent of their current range and restricted to areas known as refugia. A lack of seedling establishment has also been found at the harshest, driest sites at lower elevations. Recently a petition has been put forward to consider listing the Joshua tree under the Endangered Species Act. Joshua trees are the namesake of the park and are a major attraction to visitors. Popular media has latched on to these findings, and visitors often wonder if Joshua trees are disappearing from the park. Vegetation staff at the park are beginning to establish a network of long-term monitoring plots to document changes to Joshua tree populations. We are sampling the same sites that were sampled in the 1970s as part of a Master’s thesis, allowing us to assess change over a 40 year period. Park staff are also focusing on sampling the lowest elevation areas where Joshua trees first start occurring, as these are likely most vulnerable to the effects of climate change and where signs of decline might already be noticeable. Joshua trees can also be impacted by wildfire, and the park is looking at ways to protect potential climate change refugia for Joshua trees from burning, as much of the area identified as refugia has already burned. Despite the growing concern for Joshua trees, there are a few signs of hope, that highlight the resilience of this long-lived desert species.

Archaeology Symposium Launch – September 30, 2016

September 30, 2016 at 7:00 p.m.

The Archaeology of Joshua Tree National Park—Past, Present, and Future

Michael Newland, Sonoma State University

Joshua Tree National Park has some of the most fascinating archaeology found  anywhere in the United States. The park was home to several Native American cultures,  including the Cahuilla, the Serrano, the Chemehuevi, and the Mojave, who lived here over centuries and continue to view many areas of the park as sacred.  Many archaeologists have made remarkable finds that have changed science’s understanding of California prehistory and the metamorphosis of this rugged landscape over the past 10,000 years. This talk will highlight some of the discoveries, including the presenter’s own research, as well as discuss some of the challenges the Park and tribal advocates face in preserving this remarkable heritage for future generations.

 

 

JTNP Archaeology Symposium

Approaching 100 years of Archaeology in Joshua Tree National Park:
