Christmas Mountains

Christmas Mountains Research Symposium
To return in May 2022
Terlingua Ranch Headquarters, Brewster County, Texas

Note: Due to the Covid-19 pandemic, the meeting for 2020 was cancelled and unfortunately the meeting for 2021 has also been cancelled. The meeting continues to be a great success with increasing attendance each year between the inaugural year 2013 and 2019. The meeting will return in 2022. Check back here for details in Spring 2022.

The objective of the Christmas Mountains Research Symposium is to increase public and scientific understanding of the ecology, geology, culture and history of the Chihuahuan Desert ecosystem in the Big Bend region of Texas and Mexico.

The annual two-day symposium (now in its seventh year) highlights research by students and faculty from campuses in the Texas State University System, but welcomes contributions from researchers at other universities, federal and state agency personnel, and residents of the area who have investigated aspects of the region’s ecology, geology, culture and history. Presenters should plan to give a 12-minute talk followed by three minutes of questions and discussion. PowerPoint presentations are supported, but are not required.

The symposium will begin with an evening social and optional dinner on Monday, May 20. Each of the two following days will have field trips scheduled in the morning and presentations scheduled for the afternoon. The symposium will close with dinner on Wednesday evening May 22. Participants may wish to depart the next day but are welcome to stay and spend more time exploring the area on their own. This year we will again have multiple registration options: three-day registration ($65), which includes the social, field trips, attendance at paper sessions, and dinner Monday, Tuesday, and Wednesday evenings; two-day registration ($50), which includes the social, field trips, attendance at paper sessions, and dinner Tuesday and Wednesday evenings, and a limited registration ($15), which includes the social, field trips, and attendance at the paper sessions. Other meals can be purchased on site.

Those wishing to make a presentation should submit an abstract by TBD for 2022 meeting. Each abstract submission should indicate the general topic area (ecology, geology, culture, history, etc.) and include the title of the talk, authors’ names (with the speaker listed first) and a description of the main points of the talk not to exceed 350 words. Please plan your presentation for a general audience consisting of scientists from a variety of disciplines, as well as interested individuals from the community. Registration for the symposium is limited to 80 participants due to space constraints. Registrations must be submitted by TBD for 2022 meeting and payment may be made by most major credit cards (go to Registration Portal below).
