HESSTON — "Finding the Lost City of Etzanoa" with Dr Donald Blakeslee of Wichita State University will kick off the Dyck Arboretum of the Plains lecture series at 6:30 p.m. Jan. 29 in the Prairie Pavilion, 177 W. Hickory St., Hesston.

Possibly one of the largest prehistoric urban settlements in North America has been found. Quivira was the name which early Spanish explorers used for the territory of the ancestors of the Wichita tribe. In 1601, the founder of the colony of New Mexico led a small army onto the plains to visit the site, so there are eyewitness descriptions of the town recorded – five miles long on both sides of the Walnut River with a population of about 20,000 people.

In his presentation, Blakeslee, Wichita State University archaeologist, will discuss the proof that the site lay at today’s Arkansas City and the archaeological work that has begun to analyze the way of life of the people and their connections to distant places.

The cost of the lecture is $5 per person. Cash or credit card will be taken at the door. Reservations are not necessary.

The Winter Lecture Series will continue Feb. 26 with the Kansas state director of The Nature Conservancy, Rob Manes, speaking about "Conserving the Gems of Kansas" and will conclude on March 26 with Curtis Schmidt presenting on "Common/Uncommon Snakes of Kansas."

Educational efforts at Dyck  Arboretum will include staff hosting a Native Plant School in the coming months, including classes on Native Plant Basics, Designing with Natives, Native Landscape Maintenance, Plant Propagation, Composting and Gardening for Wildlife. Classes are $10 each or $50 for all six. Register by calling the Arboretum office at 620-327-8127 or through the Arboretum website.

The Dyck Arboretum of the Plains is a 29-acre public garden in Hesston. Its mission is to promote, through stewardship and education, the conservation and use of plants native to Kansas. For more information about the Dyck Arboretum of the Plains, visit www.dyckarboretum.org.
