I didn't understand this thing on the first map with Ratchet. After he crash lands with Quark, the two of them go searching the planet. Pretty quickly you come across a river, where you have to get to the other side to raise the bridge for Quark. The thing is there 2 ways you can get to the river, one is go straight, and hop accross the floating rock formations, but if you got up the hill to the right, there is a ledge with arrows pointing out. When you look across you will see a golden bolt, but there is no way to get across the river from there and get to the bolt. If you take the low route, and get to the other side, you can't climb up the ledge. WTF. How are you supposed to get to that Bolt?
