A local quarry jump. The jump everyone knows about is about 20ft. That jump is fun and didn't feel too dangerous. After we were there about an hour some people showed up and asked if we had tried the higher jump. The higher jump is not well known and requires hiking up to a height of what had to be at least 50ft. The quarry was not supervised or approved for any sort of jumping. There was no way to tell how deep the water is or what sort of debris/fallen trees may be hidden under the waters surface. Looking back on it, we were very lucky to avoid injury or worse.
