This vaulting was a huge undertaking, looks like.
From Wikipedia:
Hildreth Meiere, a New York-based tile and mosaic designer, working with Alexander, was responsible for much of the original interior design. She collaborated closely with the Guastavino Company of New York to create the elaborate tile vaulting, which is both structural and decorative. Buffaloes, corn, wheat, sunflowers, and wild native animals motifs are repeated throughout the building’s ornament. The theme of Meiere’s work is nature and the cultivation of the prairie.
