I was on my way to the pistol range in Pflugerville to do a little speed shooting using my brand new R57 Shot Timer. On my way, I saw an opportunity to hide a geocache. It was a quiet location without too much traffic. I quietly and discretely hid the cache and when I turned to the car, I bumped the door and the door slammed. At that exact moment, I saw lightening light up the sky. Based on the way I was facing and looking at the reflection in my car windows, I saw lightening strike four water towers at the exact same time my door slammed. This took me back to my childhood and I started counting while waiting for the thunder to arrive in order to determine the distance of the lightening strikes. Over a period of seconds, I heard four distinct peals of thunder. This was cool.
I arrived at the pistol range and pulled out my R57 Shot timer and saw it had been activated. The four times looked very familiar. The slamming of my car door must have started it and the four peals of thunder were all recorded with about the same numbers recorded on the timer. This got the mathematician in me thinking. Later that night, I did a little figuring and was able to determine the distance to each water tower from where I hid the cache. It was a good thing too. With all the weather fireworks, I forgot to record the location of the cache. I then thought that this would be a great puzzle cache. So, here is the location of the four water towers and the time in seconds it took the thunder to reach the cache location. Let’s see if you can figure out the cache location. The time it takes sound to travel through the atmosphere can vary in different atmospheric conditions, so you will have to determine the speed of sound on the night I hid the cache in order to complete the calculations.
