The coordinates are the starting point for a small multi which will lead you around the farmhouse area and is around 1 km in total length.
There is a very good car parking facility at N57 50.380 E12 07.106 and even if it should be filled with dog owners training in the area there are more possibilities along the road or at the former farm Roten nearby.
Björsjöås is a farmhouse with a long known history at the border of the Vättlefjäll nature preservative area. In this area there are many lakes popular for canoeing or fishing. Hiking is well supported by the many windshields and ready prepared places for grilling. A good chance for bringing a picnic basket. The farmhouse is hosting some small cottages for overnight staying but we do not know who is the owner of these nor the farm itself. Bigger groups seem to come together here from time to time. Perhaps anyone knows more of the ownership of this place and wants to write a note about it ?
In the vicinity there is also the cache Björsjön GC11YZ7 (visit link) for those who want a small stroll afterwards on well prepared path directly from Björsjöås. Why not combine them both ?
Access to the area is best by going the 190 NE, leaving it at Bergums kyrka and following the signs for Roten. The road splits in two just before Roten where also Björsjöås is sign marked to the left. This can ideally also be combined as a bicycling trip starting at the old railroad track in Hjällbo. The 520 bus (only 2 coupons from Göteborg) has a bus stop just where the road branches off to Bergums kyrka leaving you for a small walk.
At the coordinates for the starting point you are standing in front of an information sign leading you around the interesting remains of former agriculture in the area.
Please note that information must be collected while you make your walk reading the signs. Have a paper and a pencil available. A small mini calculator could come in handy too but should really not be needed.
The following questions need to be answered by reading the signs and assigning the letters, which are to be replaced by the figures found, according to below.
* From what year is the oldest known map of the farm ? = AAAA
* When did Krabbefejden take place ? = BBBB
* How many border stones are there on the map from the 19th century (1800 talet) ? C
* What year (decade) did one start to grow new woods here ? DDDD
* What year was the owner of the farm accused for making illegal liquor ? EEEE
With the information on hand you should do the following small math :
XXX = (DDDD - BBBB) + (EEEE - AAAA) + (C+1)
YYY = ((AAAA - BBBB) * C) + (DDDD - AAAA) - (C+2)
The cache can then be found at : N 57 50.XXX E12 06.YYY.
Please replace the cache in the same way as you found it, hopefully well hidden !
The cache is a 0,75 l transparent snap lock box with some trading items, as well as the ordinary stuff.
Here is some information for those who want to read more - but only in swedish :
Studier i Nordisk arkeologi 17:1992 Tvärvetenskapliga studier kring gården Björsjöås. Säljs endast av Göteborgs Stadsmuseum.
Have fun and enjoy the stroll !
