P&Q paid visits to Allied Rock and Washington Rock Quarries in the Pacific Northwest this month, along with the Knife River Training Center in Albany, Oregon. Below is a selection of photos from those stops, but be sure to look for in-depth coverage of the visits in the magazine in the coming weeks and at pitandquarry.com.
The Knife River Training Center (above) sits on 230 acres and features a state-of-the-art facility in Albany, Oregon, used for hands-on and classroom training.

The training center’s heated dome is 200 ft. wide and 400 ft. long. It includes a dirt arena and a concrete viewing platform.

Allied Rock, which is part of Siegmund Companies, was also on P&Q’s tour of the Pacific Northwest. Pictured here from Allied Rock are (from left) chief construction officer Gibson Kuenzi, president Andrew Siegmund and vice president of operations Alan Siegmund.
The X-Rock Quarry is key to Allied Rock’s operations. Allied Rock acquired the site in Stayton, Oregon, in 2017, rebuilding the haul roads while updating the mining methods to maximize the operation’s efficiency.
P&Q also ventured to two Washington Rock Quarries operations – including the King Creek Pit in Orting, Washington. The pit includes a high-capacity aggregate drying and bagging plant, as well as a state-of-the-art wash plant. The pit produces topsoil and sand blends, as well as specialty products like Armorstone and infill sand.
The 3,000-ft.-long overland conveyor seen here is new to the King Creek Pit. The equipment, which was originally used at a Nevada gold mine, ultimately replaced three haulers in the site’s fleet.
Washington Rock Quarries’ nearby Kapowsin Quarry is an open-surface basalt mine sitting just above the northeastern end of Lake Kapowsin in Washington state.
