“Mirasol, Looking at the Sun” is about (Pueblo chile breeder Mike Bartolo), his legacy championing agriculture and water protection in the Lower Arkansas Valley, and the fight producers there are increasingly up against amid population growth and urban spread in places like Colorado Springs and Aurora. It was co-produced by the Palmer Land Conservancy and Kristie Nackord, who brought in acclaimed documentarian Ben Knight to direct it. … She recently discussed the 37-minute film, farming and how cities are sipping water from the lower Arkansas River with The Colorado Sun.
