Saturday, May 12th, 2012 field trip
Meet at Hotel Albuquerque at 7:45 AM. Vans leave at 8:00 AM and will return at 6:00 PM.
Please see details on the 2010 field trip below, but keep in mind that the May 12, 2012 trip will be just one day to the Santa Fe impact structure.
The city/plaza of Santa Fe was so popular in 2010 that you have the option of staying in Santa Fe on Saturday night, and taking the Railrunner back to Albuquerque or the airport on Sunday the 13th. You are on your own after the vans leave Santa Fe to return to Albuquerque.

- Valles Caldera Field Trip
Since publication of the classic geologic map by C. S. Ross, R. L Smith, and R. A. Bailey (USGS), Valles-type ignimbrite calderas ("supervolcanoes").have been recognized on every continent and geologic period. Commissioned by NASA for astronaut training during the height of the pre-Apollo impact vs. volcanism debate, the map illustrates the similarities and differences between endogenic and exogenic craters. Complexity increases with diameter in both types, as both develop unstable walls, central uplifts, melt sheets, and ejecta blankets. Ignimbrites superficially resemble suevites, but their petrology reflects the constrained P/T conditions of exploding shallow granitic magma chambers. Parallel studies of calderas and impact craters during the 1960s and 1970s restored long-discredited catastrophic concepts to mainstream geology.
into Garrett’s Desert Inn near downtown (historic)
•http://www.garrettsdesertinn.com/rates.html - surf around the site to see info on the rooms, on site French bistro, heated pool, etc.
•Our discount is $109/night ($125.42 w/ tax) for a room with two queen beds; we reserved the last 20 rooms available! Call 1-800-888-2145 or (505) 982-1851 or use the on-line form (link above). Even if it quotes you a different price on-line, you will definitely get the reduced $109 rate. Tell the operator (or write in the on-line comment box) that you are with “UNM Sante Fe impact crater” group.
•Or book online and use the code “CONE” (as in shatter cone) for the night of Friday, July 23rd to the get the $109 rate
•Dinner on your own in Santa Fe
•explore the Plaza and local art …
•or make reservations for the world famous Santa Fe Opera
•Madame Butterfly at 9 PM on 7/23, website link above has info on shuttles to pick you up in Santa Fe
•or *maybe* 1 field trip van might shuttle opera fans
Saturday, July 24th
•Breakfast details coming soon (hotel does not provide)
cones and breccias of
•Paper on Shattercones: Fackelman et al, EPSL, 2008
•Jared Morrow (SDSU) will tell us about recent work (above paper) on the petrography of shatter cone surfaces and shatter cone orientation
+ Probably ~2 miles of walking
in field, dinner in
•Two options: hotel in Sante Fe or Albuquerque
return with vans to
Sunday, July 25th
back home or to
•tour of UNM Institute of Meteoritics and Lonar shocked basalt collection in late morning
•UNM IOM: Excellent meteoritics and geology museums, plus a behind-the-scenes tour of some shergottites such as Zagami
•Hand samples and optical microscopy / thin sections of Classes 2,3,4,5 shocked basalt (maskelynite-bearing through impact melts) from Shawn Wright
•Flying out Sunday afternoon/night? No problem; the ‘50’ bus runs until 7 PM and goes from UNM (80 yards south of IOM) to ABQ airport ($1, 12 min ride)
•*perhaps* one or two vans will shuttle tour participants to airport; will check when UNM vans are due back
Details on Fees:
•fee (cash or check payable to Institute of Meteoritics) to cover costs for field trip guidebook, UNM van rentals, plus food & Friday’s hotel for our UNM graduate student drivers, whom have to take a LONG course to become certified to drive the vans. We need this fee paid by cash or check and you will receive a detailed receipt listing the field trip, days, locations, etc. We implore everyone to take advantage of our vans. Please contact us if you want to drive your own vehicle. Outcrops on this field trip do not allow for 10 vehicles to park on the road side. Further, it becomes too complicated to keep track of who owes for guidebook, who didn’t ride in the vans, etc., so we have to collect the same field trip fee from everyone attending. The final cost depends upon the number of field trip participants. We hope to keep it at $60-$75.
and meals – you pay these “on your own”; we negotiated a good rate for Thursday
night’s hotel in
•Rough estimate for lodging + van fees in 2010:
•if sharing rooms: $83 (2 nights in ABQ) + $63 (1 night in Santa Fe) + $60 (vans) = about $206
own room: 2x($83.34) + 125.42 + ~$60 van/guidebook fee = about $352, and
another $42 if staying in
•Food: dinners on your own; cost for 2 lunches in the field coming soon …
