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.

 

Shatter cones and breccias of Santa Fe impact structure

Paper on Shattercones: Fackelman et al, EPSL, 2008 , including petrography of shatter cone surfaces and shatter cone orientation

Abstracts on Breccias: Tegtmeier et al., Large Meteorite Impacts, 2008 or Wright et al., LPSC, 2010 or Caine et al., GSA, 2007

* Tim McElvaine will share the story of finding the shatter cones.

Friday, July 23rd

 

Hot breakfast buffet at hotel (MCM Elegante)

We are NOT going through Santa Fe on the way to the caldera; the vans are driving “clockwise” from Albuquerque “up and around” Valles caldera and on to Santa Fe in the early evening

Field trip to Jemez Volcanic Field ignimbrites led by Wolf Elston

- 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.

Check into Garrett’s Desert Inn near downtown (historic) Santa Fe

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)

Shatter cones and breccias of Santa Fe impact structure

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

Abstracts on Breccias: Tegtmeier et al., Large Meteorite Impacts, 2008 or Wright et al., LPSC, 2010 or Caine et al., GSA, 2007

+ Probably ~2 miles of walking

Lunch in field, dinner in Santa Fe (Furr’s Buffet or downtown)

Two options: hotel in Sante Fe or Albuquerque

Staying in Santa Fe for another night?  Garrett’s will give you the discount, but your on your own (Railrunner train) to return to Albuquerque on Sunday

Or return with vans to Albuquerque to stay Saturday night at MCM Elegante ($74/night)

 

Sunday, July 25th

 

fly back home or to New York City for MetSoc (free shuttle to airport from MCM Elegante) or …

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.

 

lodging and meals – you pay these “on your own”; we negotiated a good rate for Thursday night’s hotel in Albuquerque, Friday night’s hotel in Santa Fe, and two options for Saturday night (Santa Fe or Albuquerque).  It is true that Motel 6 is cheaper, but you don’t get the airport shuttle and free breakfast buffet.  The cheaper motels in Santa Fe have no food options nearby, and our hotel is 0.17 miles (2 blocks) from historic downtown Santa Fe.  If we are going to stay in Santa Fe, we might as well be tourists and stay in a nice hotel with a variety of restaurants within walking distance.

 

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

extra night in Santa Fe rather than ABQ Sat. night: add $21 to above cost, plus $8 for your Railrunner train ticket (no vans!)

Your own room: 2x($83.34) + 125.42 + ~$60 van/guidebook fee = about $352, and another $42 if staying in Santa Fe Sat. night

Food: dinners on your own; cost for 2 lunches in the field coming soon …

 

  • FLIGHTS: Albuquerque airport (code ABQ) has most major airlines (USAir from PHX, American from Dallas, Southwest from PHX or HOU, United from DEN, Delta from ATL), so check your favorite search engine or southwest.com
    • Try to fly in Thursday, July 22nd in time for optional presentation and for a good night’s rest
    • Fly out anytime Sunday, July 25th or later (on your own) – optional IOM tour middle-late Sunday morning into early Sunday afternoon
