Tableau – A Native American Mosaic has a New Home in Loring Woods

George Morrison’s Tableau - A Native American Mosaic - being installed between 11th and 12th Street, Minneapolis.

George Morrison’s Tableau – A Native American Mosaic is being installed between 11th and 12th Streets. The handsome paving carpet, one of the historic works returning to the mall, will provide a gracious transition between Nicollet and the Loring Greenway.

The Re-Installation of Tableau – A Native American Mosaic

The granite pavement carpet by acclaimed Minnesota artist George Morrison was originally sited in 1992 at the entrance to the IDS Center where it could be viewed overhead, from the skyway, and up-close while walking on Nicollet. This location, access point for emergency vehicles including heavy fire trucks, challenged the survival of the mosaic. Weight loads combined with winter freeze-thaw conditions caused some of the two-inch thick granite pieces to crack. Salt applied in winter deteriorated the mortar and destroyed the setting bed, loosening the pavers. Several patch jobs began to detract from the mosaic’s appearance.

In 2004, the mosaic was restored and its next location was adjacent to Minneapolis Central Library and a grove of birch trees along the east side of the building. Thought to be a safer place away from heavy vehicular traffic and with only foot traffic, cracking and mortar failure continued to be a problem.

The design team for Nicollet led by James Corner Field Operations considered several new locations and settled upon the connection with the Loring Greenway between 11th and 12th Streets. This lush landscaped setting would complement the woodland imagery in the mosaic. Tableau would become the centerpiece of an ensemble of curving wood seating walls and planting beds and for the first time, instead of just walking over the mosaic, people could actually take a seat and examine it close-up.

Technical problems had to be solved before the mosaic could be re-installed. After it was removed from Nicollet in 2016, SEH, INC who has worked with the City as Construction Manager throughout the recent public art installations, produced several mock-ups to field test different methods for setting the granite.

Bob Kost, ASLA, Public Art Collections Manager with SEH, INC says the entire technical cross-section composed of pervious concrete, mortar and grout mixtures, and sealant, was field-tested over a two-year period. The mockups were evaluated prior to developing the final drawings and specifications for the re-installation.

A pervious concrete base and a modified granular mortar mix for the grout setting bed were selected because they would move water away from underneath the granite pieces; especially important during the freeze-thaw season.

Challenges continued when Yerigan Construction started to prepare the site to install the work in late August. Removing the sidewalk to inset the mosaic, they discovered that not only did it slope eastward to Nicollet but also slightly to the south – the site was a compound grade, sloping in two directions.

Imagine setting over 200 pieces of granite of different shapes, with no more than 1/4” difference in height between pieces in order to meet Americans with Disabilities standards, across a warped plane! Fortunately, the modified granular mortar mix will be flexible enough to accommodate these variations.

Twin Cities Tile and Marble Company, a sub to Yerigan Construction, are particularly skilled in setting Morrison’s mosaic. Master mason Mike Schermerhorn leads the team that includes Henry Kisumu, Jake Nelson, Adam Pettit, Rob Williams and Steve Violet. Mike says that this is the fourth time that they have de-installed or re-installed the artwork! Also on-site daily during re-installation is Kristen Gillette, conservator with Kristin Cheronis, Inc. who restored the granite mosaic.

The installation commenced after the Labor Day weekend. Over the course of the following weeks, I paid several visits to the site and produced a photo essay documenting the re-installation.

Stone Boats – A Very Minnesota Subject

If you sat on one of Stan Sears’s carved granite benches, you probably recognized how comfortable they are, but did you know that the forms are inspired by how fishes move?

When Sears proposed the sculptures, he talked about the boat theme: “The first and most direct is simply the sensual beauty of the kinds of forms that have evolved to move easily through water. So while these (sculptural) forms are not literally boats, they owe much of the elegance of their form to the functional requirements of real boats. In addition, my boat-like forms tend to be distorted, a muscular asymmetry reflecting the character of a moving fish blended with a boat form… Boats are a very Minnesota subject; we have a greater amount of coastline than even California. We are in the City of Lakes on the Mississippi River in the Land of 10,000 Lakes where there is a higher per capita ownership of boats than anywhere else in the country.”

Another contrast he found interesting – and humorous – is that these boats are overturned or sunken; the detritus on the bottom of a river. Not surprising, considering that they are made of Minnesota granite!

Sears, a professor at Macalester College, is a sculptor whose work deals with people, space and time. Because he enjoys solving problems, the field of public art attracted him. Here’s what it took to design and produce Stone Boats in 1992, his first major project.
