The gunpowder is to the bottom right side. If it isn't there, you may have already picked it up (look in your item bag). If you still can't find it, go to the Viking site (831 AD) and see what happens when you get in front of the rock cave. As a last resort, leave Time Tangled Island, re-boot Poptropica, and then come back. It may be a transient glitch in the program.
