Adding sample data to Gold King Mine spill map

Arizona Geology Blog - Mon, 2015-10-12 14:22
The USGS is making data available for sample locations and sampling parameters from the EPA Gold King Mine spill.  We are adding it to the GKM spill sample map we create. They will be releasing the water chemistry data shortly at their own dedicated GKM spill site, or it can be harvested from the  NWIS web site.

The USGS is building out a web feature and they would be delighted for feedback. It is unclear when they will go public. It in expected to be a very robust site with historic data, interactive map, remote sensing data – satellite and airborne, and more.  They are very interested in stakeholder response to this approach.

We have also received a request from the National Park Service to add biological sample data to the AZGS site so we are contacting the appropriate agencies.

Field trip guide posted online: "Geologic Diversity of Arizona and its Margins"

Arizona Geology Blog - Mon, 2015-10-12 13:45
AZGS has posted a geologic classic online for free viewing and downloading.    Special Paper #5, "Geologic Diversity of Arizona and its Margins: Excursions to Choice Areas," was published in 1987 as part of 100th annual meeting of the Geological Society of America which was held in Phoenix.  As part of the online release, we are marking down printed copies from $20 to $10 in our store, "Arizona Experience."

"The occasion presented an opportunity for the organizing committee to provide, through 34 field trips, a comprehensive expose of the geology of Arizona. Thirty-three of the field guides to these trips are included herein. Field-trip plans were made with two chief goals in mind: to provide to participants a sense of the discovery and momentum that attend geologic research and exploration in the Southwest during this, the close of the first century of GSA; and to underscore the quality of geologic exposures and the natural aesthetic appeal of the Southwest in general and Arizona in particular. It seemed very appropriate that the 100th meeting of GSA be held in the Grand canyon State"
CITATION: Davis, G.H. and VandenDolder, E.M., 1987, Geologic Diversity of Arizona and its Margins: Excursions to Choice Areas. Field-Trip Guidebook, Geological Society of America, Arizona Bureau of Mineral Technology, Special Paper 5, 422 p.

Erroneous earthquake report in Sedona area

Arizona Geology Blog - Wed, 2015-10-07 10:06
Tucson News Now has published a report of a magnitude 4.7 earthquake near Sedona on Sunday night saying they got it from the Associated Press, and quoting the Arizona Geological Survey as the source of information.    However, no such earthquake occurred.

The information and quotes in the release are taken entirely from the news story of the November 30, 2014 earthquake of that magnitude at the location.

We've alerted AP and Tucson News Now of the error and presume they will remove the story from their site.

Here's today's report as published by Tucson News Now -

Oct. 6, 2015 report -

Rock slab stabilized at Glen Canyon Dam

Arizona Geology Blog - Tue, 2015-10-06 08:05
The 250-ton slab of Navajo Sandstone peeling off the south wall of the canyon at Glen Canyon dam has been bolted into place to prevent it from falling on to power plant facilities immediately below (bottom photo).   The photo below shows the slab in the lower left area of the circle below with dozens of dark circles marking the rock bolts.  [my photo, 10-5-15]

An official at the dam said plans are to remove small pieces of the slab over time to eliminate the threat.
