ANTIQUES ROADSHOW continues its sojourn in Hot Springs, Arkansas, and host Dan Elias leads the ROADSHOW jewelry experts down the road to Murfreesboro, where they try their luck harvesting diamonds at Crater of Diamonds State Park. Back at the Hot Springs Convention Center, some fortunate finds include a magnificent portfolio of Ansel Adams photographs, signed by the photographer; a logbook containing minutes of the Arkansas Territorial Legislative Council from 1825 to 1829 - an important historical record of the time - and a newly discovered painting by renowned Hudson River School artist Jasper Cropsey valued at $150,000.
