Geocache Description:

The Mercury mystery - multistage/virtual mystery cache

There are 4 virtual geocaches in and around Idrija, each supplying partial information for final mystery cache lcation. Letters shuld be converted to numbers with Letter conversion key, which is same for all four locations. It's not neccesary that all letters are used for final coordinates. The final coordinates are calculated using secret formulas.

All spots are in walking distance. It will take about 1 to 2 hours to complete four locations, but there are many hystorical spots around. It's worth to take whole afternoon or even whole day to hike around. For last location (the Stone) try to find hidden track with stariways and nice view to Idrija. If you are not successfull on the way up, it's more asy to find the stairs on your way back.

Name Location Hint
Portal N 46° 00.048 E 014° 01.108 (WGS84) Old building. Big entrance with small entrance within.
Mine N 45° 59.987 E 014° 01.357 (WGS84) Mine/shaft entry.
Pump N 45° 59.932 E 014° 01.951 (WGS84) Old pump - info board.
Stone N 45° 59.030 E 014° 01.840 (WGS84) Stone with numbers.

Use following formulas to calculate final location:
SHAFT_NUM = LETTERSHAFT_NAME [ 1 ] & LETTERSHAFT_NAME [ 3 ] & LETTERSHAFT_NAME [ 8 ]
PUMP_NUM = (PUMP_YEAR-SHAFT_YEAR+PUMP_DEPTH)*100
MERCURY_NUM = (Mercury atomic number)*100
PORTAL_LOWER° (PUMP_NUM + SHAFT_NUM – MERCURY_NUM)/1000 + 0.013
PORTAL_UPPER° (STONE_LOWER & STONE_UPPER)/100 - 0.035

Warning

Constants 0.013 and -0.035 added due to cache final location shift to a safer location. New location is abot 20m away from previous and about 20m higher in altitude. Be careful at final location, it's on a high rock, which can be accessed easily, but there's a vertical drop about 10m if you go too far.
Please read notes (date 22. april 2007) for more details.
