Oddly enough, you won't find the Un'Goro meteor...

After many levels of bouncing around between zones for very few quests, we finally reach the Un'Goro Crater section of our World of Warcraft leveling guide. This is a zone built for all the players that love quests. You can really sink your teeth into the zone as there are a veritable ton of quests here.

Return to the base of the entry ramp to turn in the two quests there and
then head west to between the two lakes to turn in "*Finding the
Source*" and get "*The New Springs*". Keep going west to find the
"*Western Pylon*" near 22,59.
