DRI: What brought you to DRI?

Person: I was introduced to DRI through the UNLV Department of Anthropology. I became interested in coming to DRI as a graduate assistant when I learned that a position at DRI gave students the opportunity to perform fieldwork as well as write reports and plan projects for cultural resource management archaeology. In addition to this great opportunity for learning new aspects of this area of archaeology, I jumped at the chance to learn more about Native American archaeology in the Great Basin since my research focus at UNLV is primarily based in New Mexico. I also got really excited when I learned that I’d be working with historic nuclear testing resources since that’s such a major part of America’s scientific history.

DRI: What are you studying?

Person: I study stone tool technology and how it interrelated with cultural and social life at sites in the Mimbres Mogollon region of southwestern New Mexico. The time period I study was around AD 550-1130 and during this time these people changed from highly mobile foragers to living in settled agricultural villages. This resulted in changes in their social organization that I think also impacted the way they made and used stone tools. Though this is not directly related to DRI’s work, experience with similar artifacts in the Great Basin has added a new dimension to my own work.

Archaeology in the Great Basin is very focused on mobile groups and studying here and working with these archaeological sites at DRI has taught me a lot about how mobile people moved around and interacted with their environment. This knowledge has really deepened my understanding of how groups of people in my study area acted when practicing this lifeway and expanded the range of my research.

DRI: What research projects are you working on? And who at DRI are you working with?

Person: I work with the Cultural Resource Management Program team. They’re a great group of archaeologists and historians who have a variety of interesting projects in addition to their cultural resource work. My supervisor is Maureen King, who has been very supportive of my academic progress and has helped me a lot in my professional development. Though I work with a combination of United States history and earlier Native American history, Maureen is great about involving me with program projects that align with my research interests here in Nevada, which I’ll talk a little more about below.

Currently, I am working on my dissertation research which involves the stone tool study that I mentioned previously. At DRI I have mostly been focusing on working with historic nuclear testing activities for cultural resource management. Informally at DRI, I have been looking at how groups moved throughout southern and central Nevada and adjacent regions. I’m interested in how these travel routes map on to environmental features such as water sources like springs, rivers, and wetlands as well as other resource-rich areas. Since these resources included plants, animals, rocks for tools, and culturally significant areas I have a lot to work with when it comes to investigating the how and why of people’s interaction with these areas over a long period of time.

Additionally, our program at DRI has a long history of working closely with Native American groups who live in the region. Being exposed to Native perspectives on the land and environment is a really valuable addition, since they have inherited a cultural understanding of this area that only comes from lived experience and long tradition. Though I don’t presume to fully understand how previous generations of Native Americans of the Mojave and Great Basin thought about their environment and lives, being around these perspectives has really opened up my mind to ideas and viewpoints that I wouldn’t have developed on my own. I’m really grateful for that!

DRI: What are your short-term and long-term goals while at DRI?

Person: In the short term, I hope to continue making contributions to our program and its support of projects through cultural resource management.

In the long term, I want to learn everything I can during my time in our program so that I am well-situated for both academic and non-academic archaeological work. I also want to formalize some of my research interests into a developed research plan, one that ideally would contain public science-focused elements. I’m really interested in public science and supporting science education in general.

DRI: Tell us about yourself. What do you do for fun?

Person: I like to get out in nature. So hiking, camping, bouldering, and other types of outdoor activities are always a good time. I’m a sort of amateur geologist, so I also like checking out interesting rock formations and the overall geology of a place. Nevada is a really great place for all that so I have a lot of options!

When I’m not running around outside, I play music. I play a few instruments but I’m best at the guitar and I play just about any style that a guitar can do, so rock/blues, country, bluegrass, jazz and even classical music. I also like cooking and especially grilling, backyard hangouts, and spending time with my wife Lizzie and our Boxer dog Wiggles, who are my companions in all these things I do for fun. One of these days I’ll have the space to get a project car so I can finally finish learning auto mechanics without worrying about messing up my daily driver!

Preserving Nevada’s Lost City using drones

Nevada’s “Lost City,” located northeast of Las Vegas on a terrace above the Muddy River, has been lost twice before – first abandoned by the native people who built it, then later flooded beneath the waters of Lake Mead – but a team of archaeologists from the Desert Research Institute’s Las Vegas campus hopes to ensure that it isn’t lost a third time.

This summer, DRI researchers JD Lancaster, Tatianna Menocal, and Megan Stueve plan to use unmanned aircraft system (UAS) or drone technology to create high-resolution 3-D maps of the Lost City archaeological site, which consists of about 46 adobe structures that date back more than 1,000 years. Working with representatives from the National Park Service, the team will then use these detailed maps of the structures and topography to devise best management practices for the continued preservation of the site.

“The structures are set on old river terraces and lake deposits that are really susceptible to erosion, and as the level of Lake Mead has dropped, the erosion seems to have accelerated quite a bit,” said Lancaster, Assistant Research Scientist of Archaeology at DRI. “Our goal with this project is to try to figure out where erosion is particularly bad and to try some different techniques to help control that erosion.”

Lost in time

Lost City, also known as the Pueblo Grande de Nevada, was home to a small community of people of the Puebloan culture from about 800 A.D. to 1300 A.D. Here, they lived along the banks of the Muddy River, farming crops such as corn, squash, cotton and beans, and supplementing agriculture with wild and hunted foods.

No one knows exactly why Lost City was abandoned by its original inhabitants, but once the remains were discovered in the 1920s, they were mapped by archaeologists. After the construction of the Hoover Dam in 1935, the rising shoreline of Lake Mead became a threat the site.

“The area was inundated by the rising waters of Lake Mead after the construction of the Hoover Dam. Original researchers and the Civilian Conservation Corps were under a time crunch to get all the data they could while the Dam was being constructed, all the while knowing it would be lost after inundation,” said Stueve, Staff Research Scientist of Archaeology. “Fortunately, only half the site was inundated by high water levels and as the water receded from years of drought, the site was fully exposed once again and available to study.”

The ruins were studied again in more detail in 1979 through the 1990s, by which time extensive erosion had already damaged a number of the structures.

“One thing that has always been noted in the archaeological studies is the level of erosion in this area,” said Menocal, Assistant Research Scientist of Archaeology. “Entire landforms or portions of the landforms have been eroded away, so portions of the site are no longer there. In some places, entire houses are gone.”

Today, Lost City is listed in the National Register of Historic Places and managed by the National Park Service as part of Lake Mead National Recreation Area. Lancaster, Menocal, and Stueve approached NPS with an idea for a partnership to aid in preservation of the site. When an opportunity to fund the project through DRI’s Lander Endowment became available they realized the partnership was a possibility.

“We were looking for ways that we could branch out and impact the local community and the local resources around us a bit more,” Lancaster said. “We have a lot of capabilities at DRI; it’s the type of place that has the infrastructure for us to do high quality and meaningful environmental science.”

A plan for preservation

To help protect Lost City from further damage, the DRI team plans to use UAS technology to create high-resolution maps of the area, through a process called photogrammetry.

“The UAS will fly around and take a series of several hundred photos of the area of interest, and we’ll use that to essentially build a 3-D model of the surface,” Lancaster explained.

They will use the maps to identify areas where erosion has occurred in the past and present, as well as areas where they expect erosion to occur in the future. During the summer of 2020, before the monsoon season hits, the DRI team will work with representatives from NPS to design effective treatments for the erosion problem. They plan to monitor the results of their efforts using UAS photogrammetry as the monsoon season progresses.

“The erosion is focused in these deep gullies that have formed in soft sediments, and these gullies are causing damage to the site as they expand and run into each other,” Lancaster said. “So, we’re planning a paired study. We’ll install an erosion treatment in one gully, and the other gully in that pair will not get a treatment. We’re essentially testing the effectiveness of erosion treatments approved by NPS management.”

The team is still looking for funding for another component of the project, which would utilize a thermal sensor on the UAS to detect structures or stone objects that are buried beneath the land surface.

“Out at Lost City, there are probably still structures that are buried beneath sediments, that you can’t actually see,” Lancaster said. “If we could discover where they were, and discover where gullies or erosion might expose them and start to damage them in the future, we could actually prevent them from being damaged or exposed in the first place. That’s one really exciting aspect of the project that we’d love to have the opportunity to test.”
