Why, yes. Yes they did.
About two posts ago, I pointed out that there are some places where the geology is kind of...monotonous. One of those places is the vast sage plain east of Grand Canyon and Flagstaff, around the towns of Holbrook and Winslow (yes, that Winslow). The land is flat, windy and barren, hardly looking like a place of geological inspiration. And yet it is.
In the last
There was a magnitude 2.4 earthquake (orange star at right. Credit, USGS) just after 11 pm on Friday night. about 9 miles south of Flagstaff. It's possible this is another aftershock to the magnitude 4.7 quake of November 30,
A magnitude 3.3 earthquake hit northern Arizona about mid-way between Flagstaff and Grand Canyon village on Saturday, Sept. 26 at about 4:14 pm, local time. [Right, orange star marks quake epicenter. Credit, USGS]
Later that evening, at 9:23 pm, a magnitude 2.9 event occurred about 7 miles SSW of Kachina Village. This could be another aftershock to last November's M=4.8 earthquake
Houston, We Have Geology!Occasionally, I post various items that are not exotic or from faraway places. I'll be leaving for Alaska soon to run a wilderness river (the Tatshenshini) and so look for a post from that trip soon. In the meantime, here are a few odds and endsI just loved the above-the-fold headline in this mornings Arizona Daily Sun! Geology plays a prominent role in the upcoming New Horizons mission to Pluto. As you can imagine, Flagstaff has more than a passing [...]

North-Central Arizona by Paul Lindberg, 12 p. (May 2015)" is now posted online by the Arizona Geological Society http://tinyurl.com/AGS-Spring2015-Fieldtrip
According to the announcement, this geologic field trip guide circumnavigates a loop of ~120 miles from
Flagstaff to Sedona
We had aftershocks on Wednesday from both of last year's more prominent earthquakes in Arizona.
A magnitude 2.5 quake (orange dot on AZ-NM border) is likely an aftershock to last June's M=5.3 Duncan earthquake. It occurred at 3:50 p.m. local time on January 28. The yellow dot is another aftershock, M=3.4 that occurred earlier in the week.
Another magnitude 2.5 quake hit south of
AZGS geologist Jeri Young has compiled all of the aftershocks greater than magnitude 2.0 from Sunday night's magnitude 4.7 earthquake in the Oak Creek Canyon area between Sedona and Flagstaff.
The figure also shows the M=3.5 quake from November 25 in the same
The helicorder station at Flagstaff captured the records of the magnitude 4.7 earthquake last night between Sedona and Flagstaff and 11 aftershocks. Most occurred in the two hours following the main shock, with another around 5 a.m. this morning local time, and one after 1:30 p.m. this afternoon. More aftershocks are expected in the coming days and weeks. Thanks to Jeri Young here at

A magnitude 4.7 earthquake struck north of Sedona on Sunday night at 11:57 p.m. local time and was widely reported by residents across the region. One
Last night, a M4.7 earthquake occurred between Flagstaff and Sedona (just west of Munds Park). I hope it was not too scary for my friends and colleagues. It sounds like it got their attention! I agree with Professor Brumbaugh from NAU who said: "It was a large enough earthquake to be felt, but not quite large enough to really get too concerned about" (link). The USGS shakemap indicates that light shaking is reported from north Phoenix to north of Flagstaff. If you know someone who felt it; tell [...]
From USGS web siteA moderate 4.7 magnitude earthquake with an epicenter in Oak Creek Canyon woke me up here in Flagstaff just a few minutes before 11 PM last night. Woken from a moderate sleep, at first I knew it was an earthquake - but then passed it off as a dream and went back to sleep. It seemed to have a jolt followed by about 3 seconds of shaking that gradually diminished.The news coverage has been good this morning. The earthquake summary can be found here on the USGS web [...]
I’m sitting
in the airport in Milan, Italy at the start of my long journey back to
Flagstaff, Arizona*. I’ve had a wonderful week in Torino, Italy at the IAEG2014 Congress, which is held once every 4 years by IAEG. It was a very nice
conference with a huge variety of attendees from around the world (those of us
from the USA comprised of less than 2% of the 1100+ attendees). Italy and China
Today's mail brought a slick brochure from Smithsonian Journeys offering a private jet tour next June around the world of northern locales hopping from Seattle to, among others, Mongolia to Siberia to Svalbard, Greenland, and Iceland before returning home 22 days later. The Boeing 757 private jet seats up to 78 passengers in "two-by-two, VIP-style leather seats."

The Southwest Fire Science Consortium posted a video report on the Slide wildfire on Vimeo. They described it:
The Slide Fire ignited on May 20, 2014, 2014 in Oak Creek Canyon between Flagstaff and Sedona, Arizona. Firefighters first raced to keep the fire from destroying over 300 homes and cabins in the canyon, and later prevented the fire from moving into residential areas outside
This post serves as a basic introduction to who I am Professionally and Personally.
I am a member of the Association of Environmental & Engineering Geologists (AEG) and a registered professional geologist in Arizona. In September 2014 I become President of AEG. I am Senior Geologist with AMEC Environment & Infrastructure, Inc. (AMEC) in Phoenix, Arizona, though I reside in
By Alexandra Branscombe WASHINGTON, DC – Just a week after a 21,000-acre wildfire between Sedona and Flagstaff, Arizona, residents there are already bracing for mudslides that could surge down the burned slopes. These water-fueled flows of burned-out trees, loose rocks and mud can pack enough power to wipe out homes and roads. A new online hazard assessment system could help threatened communities in central Arizona and elsewhere in the western
Mosaic burn on the rim of Oak Creek Canyon. Courtesy of USFS.Many friends from across the country have been asking about the Slide Fire south of Flagstaff. The firs made national news headlines as it raced north out of the canyon, seemingly making a beeline toward Flagstaff. I was traveling at the time on the Colorado River in Grand Canyon and smelled smoke on Thursday morning while in Havasu Creek. I immediately thought of Flagstaff.The fire is mostly under control now and the first detailed [...]
The Special Session regardng the Grand Canyon and Colorado River is called, "Cenozoic Landscape Evolution of the Colorado Plateau-Rocky Mountain Region and the Carving of the Grand Canyon", (Parts I, II, III, and IV). The entire two-day special session could be considered as the 4th conference ever held to address the issue for how the Colorado River and the Grand Canyon formed. The previous three were held in Flagstaff, 1964; Grand Canyon, 2000; and Flagstaff, 2010. Of course, you can [...]
Rockfalls don't get much attention in Arizona but one northeast of Flagstaff last week injured a member of a radio tower work crew on Mt Elden, according to the Daily (Flagstaff) Sun. The article reports that the Coconino County Sheriff’s Office saying the victims legs and pelvic are was crushed by a 30-ton boulder when he tried to move another large
boulder from Elden Lookout Road.
For those of you who have been waiting - I have just added another departure on the Colorado River in Grand Canyon for 2014! This is considered the ultimate scenic trip in the American Southwest. The trip will cover 187 miles through Grand Canyon National Park in seven days.The dates are May 17 to 23 and will take advantage of the warm days and cool nights at this time of year. There will be many springtime wildflowers and clear starry nights.We do numerous side hikes to see features off of the [...]
