Christmas Mountains

Christmas Mountains Research Symposium
May 23 - 25, 2022
Terlingua Ranch Headquarters, Brewster County, Texas


Program for 2022 meeting (printable)


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 eighth 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 23. 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 25. Participants may wish to depart Thursday May 26, but are welcome to stay and spend more time exploring the area on their own. A modest registration fee will cover the social, dinners on Monday, Tuesday, and Wednesday evenings, daily refreshments and snacks. Other meals can be purchased on site.

The abstract submission form and online registration portal are now open (see below). If you plan to attend the symposium, you may wish to make lodging reservations early to assure availability.
