Snowmass Seismic Station Installation, 2005
The collaborative University of Colorado/U.S. Geological Survey Snowmass seismic station was installed near Aspen, Colorado, on June 30, 2005. This station is part of the U.S. Advanced National Seismic System and uses a satellite link to continuously relay seismic data to the National Earthquake Information Center in Golden, Colo.

Ceren, El Salvador, Archeology and Geophysics
In June 2005 we assisted CU archeologist Payson Sheets with geophysical exploration for remains of an ancient Mayan village that was covered by volcanic ash around 600 AD. We measured variations in electrical resistivity of the ground, which can help us distinguish between the volcanic ash and the buried adobe buildings.

Himalayan Nepal Tibet Seismic Experiment (HIMNT)
Photos from the Himalayan Nepal Tibet earthquake seismic experiment (HIMNT). This was an NSF sponsored project that included the deployment of 15 broadband seismometers in Nepal and 14 in Tibet from 2001-2003.

1. photos from the 2001 deployment
2. photos from removing stations in 2002, including a trek to Tengboche
3. photos from the visit of Nepali seismologists Som Sapkota and
   Sudhir Rajaure to the University of Colorado in 2003.

Seismic Refraction Experiment, Fall 2005

Geophysics Class, Spring 2005
Photos from resistivity data collection with GEOL 4130 class, Principles of Geophysics, Spring 2005. Photos taken on the south lawn of the Benson Earth Sciences Building on the CU campus.

Field Geophysics, Fall 2002
Photos from the field geophysics course at the University of Colorado, Fall 2002. Thanks to TA Joya Tetrault for the figure captions.

New Zealand Deployment
A few photos from the 2000-2003 New Zealand Marlborough Fault Zone seismic experiment. We had 10 mini-arrays of seismometers in place for detailed crustal imaging. See Wilson et al. [2004] on my publications page for some results from this experiment.

Colorado GPS Experiment
This was a CIRES Innovative Research Program funded project. In summer 2001 Fred Blume and assistants reoccupied 26 sites of the National Geodetic Survey's High Accuracy Reference Network. Repeating the 2001 measurements at a later date will provide a precise calculation of the strain field across the Rio Grande Rift and the Southern Rocky Mountains.

Vibroseis Field Trip, Fall 1999
In Fall 1999 a vibroseis seismic reflection line was run from Saratoga, Wyoming, to Steamboat Springs, Colorado, as part of the Continental Dynamics of the Rocky Mountains (CDROM) project. Large trucks shake the ground and can provide reflections from 10's of kilometers deep, showing faults and boundaries at depth in the Earth.

CDROM99
Some field photos from the passive source seismic deployment of the Continental Dynamics of the Rocky Mountains (CDROM) project. We deployed 47 broadband seismometers in two north-south lines in Wyoming, Colorado, and New Mexico. The lines crossed major Precambrian province boundaries, and the data are being used to better understand the creation and evolution of continental lithosphere.
