Thanks Brian. I had no idea there were more cinder cones in the area. I will definitely do some scouting when I know exactly where the Lowell site is located. I'm not sure what 0".84 seeing looks like (I rate seeing on a 1-10 scale: http://uk.geocities.com/dpeach_78/pickering.htm and I don't know how my scale equates with yours) but it must be special compared to what I generally find in my backyard.
