R&M Engineers took core samples of glacial till at the site of the Alaska State Capitol Building as part of the Capitol Restoration Project. The first phase involves geotechnical investigations looking at the geology under the building. The sample, taken from a depth of 54-feet, was estimated at one-million-years-old and formed by pressurization from the weight of the glacier coverage over time. Glacial till is a heterogeneous mixture of clay to boulder size particles deposited within or beneath glacial ice. Bore samples taken around the building are expected to be finished next week. R&M is contracted by Juneau architectural firm Jensen Yorba Lott.
