Visit Official Park Website

📘 Park Overview

In the early 1900s, paleontologists unearthed the Age of Mammals when they found full skeletons of extinct Miocene mammals in the hills of Nebraska -- species previously only known through fragments. At the same time, an age of friendship began between rancher James Cook and Chief Red Cloud of the Lakota. These two unprecedented events are preserved and protected here... at Agate Fossil Beds.

Painter Genevieve Bluebird

Genevieve Bluebird, an enrolled member of the Oglala Sioux Tribe, creates paintings that depict powerful images of Native American woman and traditional aspects of Lakota Sioux culture.  Born in Pine Ridge, South Dakota, Bluebird is a graduate of Flandreau Indian School. She went on to attend the Art Institute of American Indian Arts (IAIA), Santa Fe, New Mexico, as well as the United Tribes Technical College, Bismarck, North Dakota.  Bluebird currently lives in Rough Rock, Arizona, with her family. 

Art has been a part of Bluebird’s life since childhood.  While she learned the fundamental techniques of painting as a student at IAIA, she continued to develop as an artist through self-teaching and experimentation. 

Bluebird’s artwork is inspired by her studies of American Indian History and Lakota oral traditions.  Working primarily in acrylic paints, she creates realistic portraits of Native Americans.  These paintings often feature imagery of traditional Lakota life and spirituality.  Images of strong and positive female figures are a recurring theme in her work. Bluebird hopes that her art will inspire younger generations of tribal members to reconnect with their cultural values and beliefs in order to overcome the hardships  they face in contemporary society.

During her program, Ms. Bluebird demonstrates her artistic creative process and will have an array of art for sale.
