Earth and Environmental Science V3010y (2 points)

The excursion is aimed at first-year and sophomore students with little or no prior background in the Earth and environmental sciences, striking a balance between the examination of modern phenomena and examples from the geological record, and with emphasis on developing interpretations from observations. Many of the outcrops are accessible with short hikes. However, days are long, and in the absence of shade, several traverses are physically demanding when the weather is hot (more than 90° F in 2004).

Summary of Geology.

The field trip will focus on the geology of the Mono Basin and adjacent areas in the eastern Sierra -- a chance to see geology in action, and to look back through geological time, in an area of outstanding vistas and natural beauty. The terrain is spectacular due to the uplift of mountain blocks with respect to structural valleys along faults, a process that started some 35 million years ago as a result of stretching and thinning of the crust in this region, and continues today.

The field trip area contains diverse geological features, including faults, volcanoes, glacial valleys, moraines, lake terraces and outcropping lake sediments, as well as the famous tufa towers.  Mono Lake is also an important example of water demands and environmental issues. We are going to examine examples of these and other features, focusing on the processes at work, the geological history and, in some cases, competing interpretations of geological history. Our emphasis in the field will be the observations upon which the interpretations are based. The intent of the excursion is to show you some fabulous geology while you take a well-earned break from spring classes. Among planned diversions, those wishing to do so will be able to take a dip in the hot springs not far from our base at the Sierra Nevada Aquatic Research Laboratory (SNARL).

Expectations.

The excursion is aimed at first-year and sophomore students with little or no prior background in the Earth and environmental sciences. We are nevertheless going to do real geology -- this isn't Earth science for poets or geotourism. Contrasting vignettes have been selected, striking a balance between the examination of modern phenomena and examples from the geological record. There is so much great stuff to see! Working in small groups, students will make observations/collect data and develop/defend hypotheses (plausible explanations), in some cases in response to specific questions. The instructor and teaching assistant will provide help as needed, and lead discussions aimed at drawing general conclusions from specific examples. Our focus is what you can observe rather than conveying information.

Many participants will be introduced to the world of geology for the first time. For a few students, the experience will reinforce concepts that may have been covered already in formal courses in high school or at Columbia. Those who would like to find out more about the Earth sciences are encouraged to enroll in EESC V2200, The Solid Earth System, one of three coordinated courses dealing with the ocean, atmosphere, solid Earth and life from a systems perspective.

Preparation for Excursion.

Preparation for the trip will include modest background reading and several sessions to introduce the geology. We have found that such preparation is important to help students to benefit from their experience in the field. Assigned readings have been posted in Columbia University Courseworks. Sessions are provisionally scheduled as follows, at 7:30-9:00 p.m. on Sunday evenings in Schermerhorn 603. The day of week and time represent a consensus of previous participants on the optimal way to accommodate varied schedules.

Sunday, January 25. Overview of excursion.

Sunday, February 8. Global Geologic Context of the Mono Basin (Plate tectonics).

Sunday, February 15. Sediments and the sedimentary record.

Sunday, February 22. Geological record of climate change.

Sunday, March 1. The development of Mono Lake and surrounding areas.

Sunday, March 8. Final briefing on logistics. Potluck dinner.

Transportation, Accommodation, Showers, Hot Springs, Meals and Entertainment.

The group will fly round trip from Newark to Reno, Nevada, and travel in the field by van. Overnight accommodation will be provided at SNARL (Sierra Nevada Aquatic Research Laboratory; http://nrs.ucop.edu/Valentine-Sierra-Nevada-Aquatic.htm). Most food will be prepared communally. There is a fully equipped kitchen at SNARL. Students will self-select five teams of four (at least one of which will accommodate vegetarians and others with dietary restrictions). Each team will be responsible for the preparation and clean-up of one evening meal for the entire group. Your other evenings will be free of responsibility. Menus will be coordinated in advance, paying attention to dietary preferences. We plan to have evening dinner at inexpensive restaurants on two days associated with the most driving.

This is a full-immersion experience, with long days in the field. Expect to get tired and to need plenty of sleep. Leave other coursework at home. Bring a novel or self-entertainment (nothing loud). A star chart is useful. The desert night sky is remarkably clear. There is no television at SNARL.

Outline of Excursion.

(All photos by Nick Christie-Blick except where otherwise noted.)

We plan to depart each day between 8:00 and 8:30 a.m., and to return by 6:30 p.m. (Daylight Saving Time). The trip is not fully planned, as some of the planning will happen during Hemming’s field work in June, 2009.  The outline below is a possible scenario.


Saturday, March 13. Arrive in Reno- get vans, get groceries, drive to the Mono Basin- some touring involved.


Sunday, March 14. Overview of the Mono Basin (tour of Mono Lake Committee/Mono Ranger Station; South tufa, Panum Crater, panoramas of basin, fossil tufa towers).


Monday, March 15. Wilson Creek Formation (Pleistocene lake sediments that crop out around the basin- a series of 19 ash layers in the Wilson Creek Formation provide excellent local time lines.  We will use these time lines to look at the sedimentary changes at different elevations and use these observations to interpret the sedimentary evidence of varying lake level during deposition of the sediments.  We will also look for other visible evidence of environmental change exposed in the lake beds.)


Tuesday, March 16. Glacial features (carved valley, waterfalls, perched boulders, glacial polishing, grooves, chatter marks, glacial moraines).


Wednesday, March 17. Volcanic features (Mono-Inyo Craters, Long Valley Caldera, Owens River hot springs).


Thursday, March 18. Hydrology and Environmental and Ecological Issues in the Mono Basin.


Friday, March 19. Tour of “Lake Lahonton” on the way back to Reno airport.  Night in Reno.


Saturday, March 20. Return to Newark.


Grades.

The course will be graded pass/no pass. Our intent is for you to have a stimulating experience.

Cost.

The student contribution to the cost of the week-long excursion, which includes air fare, transportation, accommodation, park entry fees, course materials and food, is estimated to be $350 per student (approximately 50% of the actual cost). Endowed funds are currently being sought to underwrite this kind of activity on a continuing basis.

How to Apply.

Email applications (and queries) should be sent as soon as possible, and no later than November 13, 2009, to Sidney Hemming (sidney@ldeo.columbia.edu). Please include contact information (full name, mailing address, telephone, e-mail); year at Columbia University or Barnard College; a summary of prior Earth science courses or experiences; intended major(s) or concentration(s) if known; how you found out about the trip; and any health, dietary or other concerns. Most of the outcrops are readily accessible with short hikes, but be prepared to scramble around and spend long days in the field.

As a result of heavy demand, the trip is restricted to first- and second-year students from Columbia College/General Studies (16 places), Barnard College (2 places) and the School of Engineering and Applied Science (2 places). We can accommodate a maximum of 20 students.

Registration and Payment Schedule.

All students must register for EESC V3010 (2 units).

Each student's contribution of $350 is requested no later than December 1, so that we can go ahead with airline reservations. Checks are payable to the Department of Earth and Environmental Sciences. These may be taken to the campus DEES office (Room 557, Schermerhorn; note that the office closes at 4 p.m.) or sent by mail to Carol Mountain at Lamont-Doherty Earth Observatory, Palisades, NY 10964-8000. Please mark checks "Mono Lake " to ensure that they are credited to the correct account.

Personal Equipment Needed.

including sun hat, sunblock, and sunglasses; as well as down jacket or equivalent, woolly hat, and gloves. Bring boots with good tread suitable for clambering over rough terrain (with enough room for two pairs of socks to avoid blisters); a pair of comfortable shoes or sneakers; bed linens and towel; two one-quart (liter) water containers or equivalent for the field (Nalgene bottles are good); day pack; swimsuit; and a flashlight (essential). Leave hair dryers and similar electrical devices at home. They won't be needed, and they're incompatible with the primitive wiring at SNARL. Cell phones don't work well in many parts of the Mono area; it's too remote from population centers. The chance of significant rain is not high, but some protection is advised. It can also be windy during the spring season. Space will be limited in the two vans, particularly when we are in transit. It will be necessary to be disciplined about luggage. Soft-sided bags are packed most easily.

Geological Equipment Needed.

Students will require a notebook, pencil/eraser, scale (15 cm), and 10x hand lens. A lens can be obtained through DEES for ~$8.

Optional equipment includes a geological hammer, a small folding shovel, a small pocket knife, binoculars (or a monocular), Brunton compass, a camera and/or digital camera. Estwing hammers are sold at many hardware stores. Both hammers and knives must be placed in checked baggage to prevent confiscation by airport security.

Safety Advice and Other Requests.

None of the places to be visited is especially unsafe, so long as we follow some rules. To ensure the success of the trip, please observe the following advice and requests.

  1. Follow instructions. While we are in the field, be prepared to reassemble at pre-specified times and places. Do not wander off alone. At best, it wastes time. At worst, it is an issue of safety.

  2. Watch where you put your hands and feet, particularly when climbing. Natural hazards include rattlesnakes, scorpions, and a great many varieties of thorny plants. Do not run down hills. Loose material tends to move in unexpected ways. None of these hazards has proven to be a serious problem on past trips. Insects are not generally a problem here.

  3. On steep slopes, avoid rolling blocks onto those below you. Avoid being directly beneath others on a slope. Be especially vigilant in proximity to cliffs. Never stand close to a cliff edge. You have no way of knowing how stable the rocks are, and every incentive not to find out.

  4. Be careful when using a rock hammer in proximity to others. Shield your eyes. Never strike one hammer against another. They're made of hardened steel, and tend to splinter.

  5. Drink plenty of water to avoid becoming dehydrated, particularly at the beginning of the day. Take at least two quarts (liters) with you on hot days and long traverses. A wide-brim sun hat, sunblock and sunglasses are strongly recommended.

  6. Wear sturdy boots suitable for clambering over rough terrain. They need good tread for traction. Wearing two pairs of socks is the best way to avoid blisters. Moleskin is an excellent solution if you happen to develop blisters.

  7. The desert landscape is very fragile. Please respect it. No collecting of rocks or plants or artifacts is permitted. Leave no trash.

  8. Efforts will be made to take pit stops wherever convenient. Toilets are not widely available once we leave population centers, and there is very little cover in the desert. Please respect the privacy of others. Bury all waste. Do not pollute water sources.

  9. We'll be living and travelling in close quarters. So treating others with respect applies everywhere and at all times. Stay relaxed. Chip in with chores that need to be done, without being asked. Do your part to make the trip a success. Respect quiet hours.

  10. The drinking age for alcohol in California is 21. No consumption of alcohol is permitted during the day. No open (or opened) alcohol containers are permitted in vehicles under California State law. No illegal drugs. The conspicuous display of good judgment will be appreciated. Offenders will be sent home at their own expense.

  11. For reasons of insurance, only the field-trip leader and teaching assistant are permitted to drive the vehicles.

  12. Either of us can be consulted in case of any difficulty.

Emergency Medical Arrangements.

First aid kits will travel with each vehicle (under the second seat, by the door). In emergency, the nearest medical facility is in Mammoth Lakes. All students should be sure to bring evidence of health care coverage (either Columbia or private plans), along with any medication needed during the excursion.
