The Mission Objective Scan the chasm in Destiny: The Taken King.

“Let your Ghost analyze your surroundings for a way across the chasm.”

“Scan the chasm” is an objective in the mission The Dreadnaught in Destiny: The Taken King


When you make it to the Chasm with a bridge, you will see the stones in front of you disappear. Cayde will talk with Eris about what is allowing this, and she will tell him it is some kind of "resonant spell". Pull out Ghost and have him scan the area. You will see various stones appear in front of you. Head over to the right to find the start point for the bridge.
