Planetary Geologic Mappers Meeting serves two purposes. In addition to
giving mappers the opportunity to exchange ideas, experiences, victories,
and problems with others, presentations are reviewed by the Geologic Mapping
Subcommittee (GeMS) to provide input to the Planetary Geology and Geophysics
Mapping Program review panels consideration of new proposals and
progress reports that include mapping tasks. Funded mappers bring both
oral presentation materials (slides or viewgraphs) and map products to
post for review by GeMS and fellow mappers. Additionally, the annual meetings
typically feature optional field trips offering earth analogs and parallels
to planetary mapping problems.
Mappers Meeting, June 18-19, was convened by Tim Parker, Dave Senske,
and Ken Tanaka and was hosted by Larry Crumpler and Jayne Aubele of the
New Mexico Museum of Natural History and Science in Albuquerque, New Mexico.
Oral presentations were given in the Museums Honeywell Auditorium,
and maps were posted in the Sandia Room. In addition to active mappers,
guests included local science teachers who had successfully competed for
the right to attend and listen to the reports. It was a unique pleasure
for mappers to have the opportunity to interact with and provide information
to teachers responding so enthusiastically to the meeting presentation.
June 17, Larry and Jayne conducted an optional pre-meeting field trip.
The flanks of Rio Grande Rift, east and west of Albuquerque and Valles
Caldera north of town presented tectonic, volcanic, and sedimentary examples
of the Rift and adjoining areas analogous to observed features on Mars
and Venus. The arid but volcanically and tectonically active environment
of New Mexicos rift valley enables focus on features that appear
morphologically young and spectacular in satellite images and digital
relief models. The theme of the trip was to see what, at orbiter resolution,
"obvious" geologic features look like at lander (outcrop) scales.
Trips to the top of the rift-flanking mountains (Sandia Peak, 10,600 ft)
and the Valles Caldera, as well as various active spring deposits highlighted
remarks from the host, Larry Crumpler, opening remarks by Tim Parker and
Dave Senske and a report on mapping program status by Ken Tanaka, the
mappers oral presentations began the morning of June 18, with a
session on Venus Geologic Mapping. The afternoon continued with an exciting
USGS Planetary GIS on the Web (PIGWAD) demonstration and ended with an
open discussion of issues in planetary mapping. Posted maps of Venus quadrangles
were viewed during the morning break.
Mars Geologic Mapping session began with a pep talk from Tim Parker encouraging
mapping community input to the MER landing site selection committee and
continued with Steve Saunders describing the potential contribution of
Odyssey Mission data to the geologic mapping of Mars. A Mars map poster
session was held during the morning break, and the meeting was adjourned
mappers meeting on Tuesday, attendants were treated to a "Field trip
to Mars." The Institute of Meteoritics at the University of New Mexico
houses an outstanding collection of meteorites, including those that have
been identified as originating from Mars. The Institute tour featured
examples of most of the different lithologies exhibited by martian meteorites
identified to date, as well as some of the analytical tests (scanning
electron microscope) they are conducting on specimens from ALH84001.
Wednesday, June 20, featured an optional post-meeting field trip to see a travertine quarry and nearby sites of travertine deposition, the Very Large Array near Socorro, and other volcanic features within the Rio Grande Rift..
