This cache was originally a multi with glow paint on the container to help you locate it, but the glow paint evaporates or gets washed off in the rain during the monsoon, so that didn't work long term. So the container is hidden in another spot nearby. See hint.
From the yellow post, look for the cache. The cache is within 25 feet of the yellow post, in an obvious place. I am revealing the final coordinates on the cache page to avoid archiving.
