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 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 Sunday, May 19. This year we will again have multiple registration options: three-day registration ($95), which includes the social, field trips, attendance at paper sessions, and dinner Sunday, Monday, and Tuesday evenings; two-day registration ($75), which includes the social, field trips, attendance at paper sessions, and dinner Monday and Tuesday evenings; and a limited registration ($25), 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 May 3, 2024. Each abstract submission should include the title of the talk, authors’ names and institutional affiliations, and a description of the main points of the talk not to exceed 350 words. Please plan your presentation for a general audience of scientists and students from a variety of disciplines, as well as interested individuals from the community. Visit the symposium web site to access the abstract submission form.

Registration for the symposium is limited to 80 participants due to space constraints. Visit the symposium web site to access the online registration and payment site. Registrations must be submitted by May 3, 2024 and payment can be made by most major credit cards or by electronic check.
