It's that time of year again for a unique phenomenon in the Superstition Mountains: the iconic cougar shadow! Twice a year, around the spring and fall equinox, a shadow is cast on the mountains that looks just like a prowling cougar. You'll likely have the best chance of checking out the shadow, weather permitting, starting this weekend. #abc15 #arizona #shadow #thingstodo #apachejunction #spring #superstitions #az365
