This fascinating badlands-type area in the Colorado prairie about 30 miles east of Colorado Springs is a well-kept secret. And it’s nothing short of spectacular, with its gullies, chasms, spires, overhangs, hoodoos and sculpted walls carved out of brightly colored clay deposits in layers of snowy white, rose pink, golden yellow and purplish mauve. No description truly does it justice — you have to see it for yourself. Join an El Paso County Parks Naturalist on a hike to experience the wonders of Paint Mines Interpretive Park, 9 to 11 a.m. Saturday. You’ll learn all about the physical and historical features of this fascinating pocket of Colorado and get an eyeful of stunning scenery. Cost is $5 per person, and you must be at least 12 years old. Take a hat, sunscreen and water. The park is at 29950 Paint Mines Road, Calhan. Meet in the parking lot before 9 a.m. Details: Reservations required, 520-7880 (El Paso County Fair line), directions,
