Field Trip #1: Jemez Volcanic Field and Northern Rio Grande Rift Tectonics

This trip will introduce participants to the massive volcanic eruption that produced the Valles Caldera and the associated tectonics of the upper Rio Grande Rift; it is a good follow-up to the special session about the neotectonics of the Rio Grande Rift and Colorado Plateau.

This excursion will depart from the Santa Fe Hilton at 7:30 a.m. and return around 6:00 p.m. A light morning snack and box lunch will be included.

We will begin with a stop to examine the Bandalier Tuff associated with the Caldera collapse 1.2 million years ago, and we will visit Bandalier National Monument for examination of both volcanic features and pre-Pueblo ruins. The route will continue up into the Caldera (now protected as the Valles Caldera National Reserve) for viewing and discussion of the features within, including post-collapse resurgent domes. We will then cross the Caldera and descend the southern flank of the volcano with stops at volcanic and tectonic features along the way, returning to Santa Fe via State Route 550 then north on Interstate 25 from Bernalillo.

Participants should wear sturdy shoes or boots and warm gear, including gloves, sunhats, sunscreen, and something water-resistant. No strenuous walking is anticipated but we will be making stops at elevations up to 9,000 feet. We may encounter cold winds and snow. Some stops may depend on weather and road conditions. Don't forget your camera!

Field Trip #2: Central Rio Grande Rift Neoectonics & Volcanism

This excursion will depart from the Santa Fe Hilton at 7:30 a.m. and return around 6:00 p.m. A light morning snack and box lunch will be included.

The buses will head south from Santa Fe. We will examine fault exposures in the Albuquerque area and continue south to Socorro, where we can examine tectonic features and the varied rift volcanism in the Socorro area, including unusual bimodal volcanic features. This trip should serve as a nice follow-up to the special session on the Rio Grande Rift and Colorado Plateau.

At Socorro, this field trip will split into two groups according to the interests of the participants.

Field Trip #2A: Additional Middle Rio Grande Rift features and PASSCAL Center

This field trip option will include additional visits to volcanic and tectonic features of the Middle Rio Grande Rift, plus a visit to the IRIS PASSCAL Instrument Center on the New Mexico Tech campus. This trip will include guides from the New Mexico Bureau of Geology and Mineral Resources and New Mexico Tech to discuss volcanic and tectonic features observable in the Socorro area.

No strenuous walking/climbing is anticipated; however, participants should bring sturdy footwear for investigating trench sites or fault/rock exposures, and warm gear including gloves, sunhats, sunscreen, and something water-resistant. Some stops may depend on weather and road conditions. Don't forget your camera and a pencil or colleague for scale!

Field Trip #2B: Trinity Nuclear Test Site

As a follow-up to the nuclear monitoring special session, we have tentatively scheduled a trip to the Trinity Test Site on the White Sands Missile Range. This is the site where the world's first atomic bomb was exploded. This site is generally open to the public only two days a year; however, because SSA members include a sizeable number of verification seismologists, we have arranged a special opening for interested meeting attendees.

This trip will be led by Terry Wallace, who has been a leader in the seismic nuclear monitoring community for many years. Please be aware that this is a long day of driving, but with both the Albuquerque fault exposure stops, scenery, and commentary en route, it should be a great trip.

IMPORTANT NOTE: Special security requirements exist for access to the Trinity Site. U.S. citizens must have an official government picture I.D.; we recommend a passport, which is proof of citizenship. All foreign visitors must have a passport and visa. We are required to provide a complete list of participants to the White Sands visitor office before 18 March 2008, so we cannot accept last-minute sign-ups. If you are interested in this trip, please register early! All foreign nationals must provide passport and visa information by 18 March 2008. You can send your documentation to SSA. Note that photography at the White Sands Missile Range is prohibited except for the Trinity Site and the McDonald Ranch House. In addition, access to the test site will depend upon the mission schedule for the missile range. Thus it is possible our access will be denied with little advance notice and we may instead join our colleagues for Trip #2A.
