You may have seen this beautiful sculpture as you descended/ascended the Spanish Steps. This area is distinct in character although not separate geographically and provides you an excellent opportunity to learn about a hidden geological gem.
As you walk around you will notice that this is actually a fresh water spring that is entirely drinkable. Many take advantage to fill there bottles and sample the cool fresh taste of this wonderful naturally occuring spring since they are already here to admire the touristy stuff as well. This water is transported via aqueduct, bringing water from the Salone Springs, nearly 20 kilometres from Rome. What is even more amazing is the remarkable quality of this water source.
While you are here, feel free to take a picture of yourself to share with us in your log.
The area is quite interesting, since it is below the normal water level and so was subject to a tremendous amount of flooding from the Tiber River until walls were built. In 1598 there was a horrible flood and a boat was brought into the Piazza di Spagna and so in memory of that event, this monument was created. Taking advantage of the cool fresh water that comes such a long way to enter the middle of the city.
In order to log this Earthcache there are a couple things that are needed:
1. Use a container of measurable volume and a stopwatch to calculate how many liters per hour come from the spring? Please take readings from all points as they vary in volume and will affect your overall measurement. Please do not attempt to climb into the fountain for the central sources, make a hypothesis for these if you are unable to reach them safely.
2. What magnitude would that make this spring based on the chart below?
1st Magnitude = (greater than 100 cfs* or 64.6 MGD^)
2nd Magnitude = (less than 100 cfs to greater than 10cfs or less than 64.6 to greater than 6.4 MGD)
3rd Magnitude = (less than 10 to greater than 1 cfs or less than 6.4 to greater than 0.64 MGD)
4th Magnitude = (less than 1cfs to greater than 100 gal/min)
5th Magnitude = (less than 100 gal/min to greater than 10 gal/min)
6th Magnitude = (less than 10 gal/min to greater than 1 gal/min)
7th Magnitude = (less than 1 gal/min to greater than 1 pint/min)
8th Magnitude = (less than 1 pint/min)
*cfs = cubic feet per second
^MGD = million of gallons per day
