This portion of the Yellowstone River is insane! It is downstream of the Grand Canyon of the Yellowstone which has some unbelievable waterfalls. It was a 14 mile hike overall. Long day....and you cant tell by the picture, but the bank was covered with fisures which were spitting out steam and hot water. A crazy place! But on the first cast a huge cutthroat slammed my hopper, unfortunately this one cam unbuttoned. All the cutthroats in this area were crazy bright red!!!! Awesome day!!!!!
