Cinder Pit is a small cinder cone, located north of Blue Lake Crater, which is now occupied by a basalt volcanic plug. A narrow lava flow sits a few hundred feet to the east of Cinder Pit, sitting on top of oxidized glacial deposits. Another two cinder cones are located nearby, with heights of and above the northern and northeastern flanks of the Black Crater volcano, respectively. Another line of volcanic vents lies to the south.
