The original incarnation of this cache, Massacre in Austin (GCQMRD), was the second cache that FiedoGang ever found (in December 2006). The location is within Fiedo's Neighborhood in a lovely spot along Shoal Creek. We were inspired to reactivate this in response to a thread on the CenTex Geocachers listserv asking about caches near waterfalls, regardless of how small.
The following paragraph is adapted from the description of the original cache, which has been DNF since October 2008 and was archived in April 2009.
This area is wheelchair accessible until the last 20 feet or so, where someone in a chair would need help. This is a great park you and your family will enjoy. Somewhat secluded but lots of muggles after work and in the mornings jogging and biking, so be careful when logging the cache. While you are there you may find some tranquility. Be sure to read the interesting -- if not extremely significant -- history of the area on the plaque across the creek (there are also a pair of signs just north of GZ).
Please be sure to re-hide carefully. There are lots of hikers and bikers on the trails.
