LAND OF LEGEND...AND DANGER Cache Cañon lies well outside Rock City in the Colorado high country. It was named for a legendary cache of gold hidden there, and now it's reputed to harbor a band of hold-out Indians. Although no one in Rock City has ever seen the band, the Terwilliger brothers, who regard the cañon as part of their range lands, are convinced the hold-outs are stealing livestock from them. But even the Terwilligers have something else to worry about when three strangers are seen in the caon with surveying equipment. Speculation about a new railroad spur runs rampant...until the local blacksmith identifies one of the strangers as wanted for bank robbery in Texas. And when the stage is robbed, the posse runs head on into something nobody could have suspected.
