Welcome to the PMC Lite!!!
This series was created in response to the many people who wanted a puzzle series, but did not want anything as difficult as the Puzzle Masters Challenge.
This series is meant to be fun and get those cachers, who are not normally interested in puzzle caches, to try their hand at them and realize that they are not as bad as they seem.
It is meant to be fun and entertaining and take you many places in the Mid-Atlantic region.
The caches in this series will all be released sporadically between now and the PMC puzzle event in June.
So have fun, begin to find these caches and collect the clues in each cache you find. They will eventually lead you to the final.
If you would like a list of all the caches in all the PMC series, you can find it here. It is a work in progress, but will contain all the caches and their creators as they are released.
Hope you have fun and thanks for visiting!!!!
The Black Hole
Black holes form when stars collapse. Black holes are unbelievably dense and compact, and possess such a HUGE gravitational pull that nothing, even light, can escape them (that’s why the holes are black). Since light doesn’t emanate from one, a black hole can’t be directly observed but its existence must be inferred from other observations.

Recently, a star collapsed near Liberty Reservoir and formed a black hole. Unfortunately, as with all black holes, this one can’t be detected. But we know that it is sure to be there since observers were watching the star as it collapsed. One onlooker recorded the locations of four of the star’s five points, shortly before it vanished, and that is what we have to go on.

Point 1: unavailable (bad data)
Point 2: N39 23.393 W76 52.925
Point 3: N39 22.610 W76 53.253
Point 4: N39 22.610 W76 54.315
Point 5: N39 23.393 W76 54.643
The black hole will be at the center of the star and, as you may have already guessed, that’s where the cache is hidden. It only takes a bit of algebra, geometry and trigonometry, along with a coordinate calculator such as FizzyCalc, to figure out the spot. FizzyCalc is a valuable free program that doesn't come with directions, but is well worth the small time investment it takes to learn. (get FizzyCalc)
Here is a suggested solution approach. Refer to the star sheet for more insight.
1. Find the distance and bearing between any two adjacent points using FizzyCalc.
2. Determine the distance from any point to the center by calculation.
3. Determine the bearing from any point to the center by simple math.
4. Calculate the center coordinates by projection, using FizzyCalc.

Note: A code letter/number is in the cache container. Record the information if you are participating in the PMC Lite cache series.
