The Utah Museum of Natural History will feature its 15th annual "What's in the Basement" event on Saturday from 9:30 a.m. to 5 p.m. This year's theme is Bugs, Bats and Bones.

In this behind-the-scenes event, visitors may tour all the back rooms, which house 99 percent of the museum's collections. Visitors can talk with staff members about various collections not on display.

In addition to the tours of the back rooms, the museum will offer the following activities: excavate a "pit house" as archaeologists do, see "The Bug Brigade," observe how DNA builds a living creature, watch a pine cone open, see a shell collection, and more.

Also, the herbarium will show how plants, bugs and fire have an interconnected world, the anthropology department will show how bugs played a utilitarian role in past societies, and the paleontology department will show fossilized bugs.

Admission is $6 for adults, $3.50 for children. University of Utah students are free with student ID. For more information visit www.umnh.utah.edu or call 581-6927.
