Narrative:

I was the first officer on a flight out of durango, co. The conditions were good VFR and the captain and I felt we could depart on a VFR climb out of durango and provide our own terrain separation. Due to some extra time on the ground in dro, the captain picked up an IFR clearance to montrose, co, while we were still on the ground. I didn't listen to the clearance, but assumed he had requested and been cleared for the VFR climb. While climbing out the captain instructed me to make the climbing left turn on course. Later after the controller at ZDV inquired about our position and altitude. I realized we hadn't been cleared for a VFR climb. We were required to follow the departure procedure out of dro. Conditions were good VFR and safety was never compromised.
