rising and falling in my rural water well, a HOBO water level data logger is placed in the 300 ft (91 m) deep well as part of a regional project. This intelligent device stores and transmits water level data by Bluetooth, and corrects for atmospheric pressure effects. Hey, it’s the 21st century, you know.
Former colleague Dr. C. Pritchard (EWU Geology) measuring the static water level with a well sounding tape and preparing the data logger for installation.
The water level measuring tape indicates the static water level is 223 ft (68 m) below the lip of the metal collar. The data logger is the shiny metal device and will be suspended by a cable to nearly the bottom of the well, hanging slightly above the pump.
it is imperative that one continues training and honing their skills through time, so today I once again took the magnificent Zamboni out on the ice at the University Recreation Center. It was a terrific review on the operation of the boxy behemoth conducted by geology undergraduate student Silas. Informative and fun!
Silas backs the Zamboni out of the garage and onto the ice.
Yours truly behind the wheel, zooming along at 5 mph (8 kph)! Although I wanted to feel the wind in my hair, I wore the ball cap to keep my hair out of my eyes at this blistering speed.
Driver’s point-of-view over the long hood. It does take some real skill to command this three ton beast but it pirouettes on a dime.
But, honestly, Zodiac MilPro MK4s are way more fun to drive! Happy geologist and Zodiac captain examining turbidites at Gold Harbour, South Georgia, in 2018.
with remotely operated and solar powered Flock cameras, engaging in unconstitutionally broad and warrantless surveillance of all citizens. Eight such spy cameras have been installed in my rural community in eastern Washington in a clear violation of civil liberties, and seemingly in violation of state law as well. Shame on the mayor, members of the city council and police chief. George Orwell's 1949 novel 1984 was meant to be a cautionary tale and not an instruction manual for government!
Flock spy camera violating the 4th Amendment.
Helpful link: See if you are being spied upon where you live.
20 August 2026 UPDATE: All eight Flock automated license plate readers have been deactivated in the community and will be dismantled, this according to the police chief. Privacy rights and common sense prevails! I’m not sure if my repeatedly contacting him, the mayor, the Washington State Attorney General’s Office and local newspaper exerted any pressure to reach this proper decision.
on the Pend Oreille River at the US-Canadian border, a concrete arch-gravity dam constructed in 1967 for hydroelectric generation, was nothing short of excellent. A big thank you goes to the engineers from Seattle City Light that owns and operates the structure for a terrific exploration of the facility.

that occurs tomorrow morning when I aspire to photographically capture the “triple sunrise” behind Castleton Tower. Fire smoke in the air last year frustrated my efforts and I’ve been patiently waiting for 364 days to try again.
This morning, out on the bike, on the trail beneath the Tower. Helluva back yard.
My calculations indicate that the show starts around 6:45 am MDT tomorrow.
DISAPPOINTING UPDATE 21 June 2026: The summer solstice has arrived, as well as the fire smoke! A large range fire southwest of Provo has flooded the atmosphere with a smoky haze this morning. Dang. What a difference a day makes. I’ll have to try again next year.
is ready for the forecast high temperatures this weekend. The blower was lubricated and the original water pump was replaced with a new one that is much quieter, while the aspen wood pads were replaced last year. I’m grateful that a Wi-Fi connection to the Internet wasn’t required for the pump. It’s very simple tech that works extraordinarily well.
but its important nuclear legacy will never be forgotten, having served as the hub of the most productive uranium mining district in the nation. The former company townsite has been erased from most maps following complete environmental remediation of the valley.
Wide panorama from the Star 13 mine portal showing the San Miguel River canyon where the former town and uranium mill was located. Recent remediation efforts resulted in the dismantling of buildings and excavation of radioactive waste and the debris is now sequestered in several containment cells south of the former town site.

in the San Miguel and Dolores River canyons, built between 1888 and 1891 by very determined miners working a gold placer deposit further up the canyon. Imagine trying to build this incredible project today!
Remains of the five mile-long wooden flume above the San Miguel River, still clinging to the sandstone cliff after more than 130 years.
Closer view of a section of the wooden flume as seen from an overlook from above, on Colorado 141 north of the former townsite of Uravan.
View from below at a partially restored section of the historic flume. The flume only operated several years after its completion, following which the wooden beams and planks were scavenged and re-purposed for other uses.
Around the nose of a meander bend, the hanging flume hugs the escarpment above the San Miguel River, a short distance above its confluence with the Dolores River.
after being little used for more than 60 years, since the time when the ranch was subdivided into five acre parcels that now comprise our small rural community. Considerable sedimentation has occurred in the 180 foot deep - 16 inch diameter (55 m - 0.4 m) bore that is located mid-valley and will have to be jetted out before pump installation.
Once fully refurbished the new landowner will allow the Castle Valley Fire Department access to the high yielding well for use in emergencies. A big thanks in advance!
of legally diverted water from Castle Creek, now being performed digitally and remotely since the Utah Department of Natural Resources has just installed a real-time monitoring point using a solar powered sonic water level sensor and radio transmitter. Previously, someone would have to visit this site and visually read the staff gage in the Parshall flume through which the water is flowing in order to calculate the flow. This new system is undoubtedly calibrated to the old staff gage, and likely radios the data in real-time, or perhaps daily.
Newly installed electronic gaging station next to Castle Creek above the town of Castle Valley. Note the metal Parshall flume box through which the water is flowing, away from the viewer in this image.
The sonic water level sensor at the upstream end of the Parshall flume. Note staff gage on side of flume.
The diverted water is claimed under three water rights granted in 1885, 1891 and 1933 for 2.0, 1.033 and 1.9172 cfs (cubic feet per second) respectively according to Utah DNR records.
UPDATE: An additional remote water gauging station has been installed on the 14-inch diameter iron pipe that transfers water from the point of diversion to the fields for irrigation lower in the valley. This is about 1.1 miles below the point of diversion seen above.

of low-, mid- and high-powered rockets occurred over four days at the National Sports Launch West event, bringing together more than 250 rocketeers from across the country for the Memorial Day weekend near Alamosa, Colorado. Here’s one of the first high-power rockets heading to 44,000 feet (13,400 meters) to kick off the event!
The high altitude launch site lies at 7,600 feet above sea level in the San Luis Valley with 80 launch pads/rods/rails/towers on the firing range. There’s nary a tree for miles and miles in any direction.
All launch pads and rockets on the range are fired by the Launch Control Officer and their staff of assistants, pad managers and spotters.
All rockets to be flown are first inspected by Range Safety Officers for flight worthiness prior to launch, no matter the size, both large and small.
GPS radio tracking frequencies must be managed so as to avoid conflicts during flights.
Basic kits were generously donated by Estes and the rocket engines by Chris’ Rocket Supplies for the kids.
Many vendors were represented at the event and a lot of business was conducted on the site.
in the payload bay of my high power model rockets that allows for accurate flight telemetry in real time, and also assists in locating the rocket after touchdown by transmitting its location. Today’s first test flight with the device went exceptionally well and provided a wealth of interesting flight data.

Distance between launch and touchdown points is about 100 yards/meters.
given that AI-driven functionality is being incorporated into nearly all software and apps. My neighbor and riding companion wanted a snap of himself riding across Castle Creek, however, the flow had been diverted leaving a dry channel at the singletrack crossing. Photoshop’s “Generative Fill” function nicely simulated a gently flowing stream where one does not exist. Remarkable.
absolutely demands a rocket launch. Willing to comply, Nike X achieved a 576 foot (176 meter) apogee on a “C” engine on a 48 second-long flight.
Nike X and me. The Aerotech wireless launch controller seen attached to the tripod works fantastically well, allowing a greater standoff from the pad, using Bluetooth and your smartyphone.
in the 21st century with a historic launch and capture of the largest object ever put into space early this morning. It’s unfortunate that this incredible accomplishment isn’t receiving more news coverage.
I’m not so sure that Elon Musk isn’t an alien.

It’s pretty clear that NASA needs SpaceX more than SpaceX needs NASA. Per aspera ad astra.
in remote northern Utah displays all the rocket engines and missiles they manufacture at full scale, now under corporate ownership by Northrop-Grumman. I have an enormous case of rocket envy.
The rocket garden is free and open daily to the public and includes interpretive signs and related displays. Well worth a visit if you’re heading to the Golden Spike National Historical Park which is nearby.

in southeastern Washington where I hope to earn my Level 1 certification in order to purchase and launch bigger rocket engines in my larger/heavier model rockets. I will fly the 56 inch (142 cm) tall Aerotech HV Arcas for the certification flight, a 60% scale replica of the actual high velocity Arcas sounding rocket historically used for atmospheric research.
The Aerotech HV Arcas and the Aerotech Arreaux model rockets. The smaller and sporty Arreaux should reach 3,000 feet on a "G" engine according to computer simulations.
Based on simulations using OpenRocket software that utilizes basic physics, aerodynamic principles and the standard atmospheric model, the HV Arcas model rocket should soar to a half-mile high apogee in a flight lasting two minutes long on a “H” rocket engine. A Jolly Logic Altimeter Two will be onboard during the cert flight in order to record flight data.
