In the Western Altepa Desert, there is a gate marked by four colored columns. This is the Altepa Gate and it leads to the deepest parts of the Quicksand Caves. The gate is locked, but can be opened by activating the four colored columns. * Note: As of the 2011 Update introducing the Open Sesame Quest. The weight switches needed to get to the 4 color columns can be opened solo on any race after obtaining Loadstone.
