Partnering with philanthropist and businessman, Hyrum W. Smith, he planned to create a space to tell the stories of Utah's ancient inhabitants and pioneer settlers.

Seven Nielsen designed the amphitheater complex which included a 45,000-gallon water holding pond, a river spillway, and a drainage system for the flash-flood sequence in the inaugural run of the musical production of Utah!.

(book by Robert Paxton, lyrics by Doug Stewart, music by Kurt Bestor and Sam Cardon, and production design by Seven Nielsen) a dramatic retelling of the founding of southern Utah through the eyes of Jacob Hamblin, an early pioneer called by Brigham Young to settle the city of Santa Clara and to make peace with the Native Americans in the region.

In 1998, the book and lyrics were completely rewritten by Tim Slover and Marvin Payne, creating a fictional storyline that emphasized the peacemaking efforts between pioneers and native peoples.

The production was remounted one final time for an abbreviated fall season in 2002, with Stallion Cornell providing yet another new book based on the 1996 version of the show.

The first season of this new format consisted of a double bill of Joseph and the Technicolor Dreamcoat and Seven Brides for Seven Brothers, both of which were wildly successful[clarification needed] with visitors from all United States and 25 other nations.

In 2002, productions of Annie Get Your Gun and Joseph and the Technicolor Dream Coat broke all previous box office records.

In 2005, under the direction of the new artistic director Scott Anderson, Tuacahn commemorated their tenth season by presenting Beauty and the Beast and a third production of Joseph and the Amazing Technicolor Dream Coat.

In 2006, MTI selected Tuacahn as one of eight regional theaters in the United States to present the first post-Broadway semi-professional productions of Les Misérables.

This concrete riverbed was installed during initial construction to facilitate a massive 55,000 gallon flood of water that comes from the back of the canyon and across the stage toward the audience.

It is part of the Tuacahn High School for the Performing Arts facility, though semi-professionally staged productions have been featured in this theater in the past.

The black box theater and dance studio are used primarily as working spaces for school classes, rehearsals, and special events.
