Marenakos Rock Center in Preston presents “Super Masons,” part three of its free series on what people are doing with stone, 10 a.m. to 3 p.m. Saturday, Aug. 20. at the rock center, 30250 S.E. High Point Way, Issaquah.

The event will feature masons Kyle Schlagenhauf and Matt Driscoll, presenting some of their works and taking questions from the audience. The masons will also offer a demonstration on their stone-working.

Schlagenhauf is the owner of Green Man Builders, where he combines a vision of beauty within utility in private and civic projects. In 2010 he participated in the Stone Foundations Japanese Castle Rampart Workshop in Ventura, Calif., and was introduced to Suminori Awata, 15th generation master stone mason from Japan and the Anoh style of dry laid building.

In 2014, he worked with Suminori Awata during the “Rock, People, Chisels” Ishigaki workshop at the Kubota Garden in Seattle. He was lead mason in the 2010 construction of a dry stack stone amphitheater at Mather Point on the South Rim of the Grand Canyon National Park and in the past year, he was part of the Portland Japanese Garden’s “Cultural Crossing” expansion, helping to build a 20-foot tall by 185-foot long Japanese castle wall.

Driscoll began his work with stone in 1996, after an 11-year apprenticeship with master stonemason George Gonzalez. In 2007, he began to specialize in dry-stone work, working on many projects of his own. In 2010 he continued a now 18-year working relationship with Schlagenhauf, shifting from private to completing several major public projects, the most recent being the Portland Japanese gardens.

He continues to create functional and sculptural stone works in both public and private venues, linking beauty, function, innovation, and space with what he calls the “dispositions of stones.”

The event is free and a sandwich lunch will be provided by Marenakos. Seating is limited. Contact the rock center at (425) 392-3313 if you plan to attend.
