Marjalahti is one of four witnessed pallasite falls as of 2014. The only work I was able to find that thoroughly described the event is in German: Die Meteoriten von Hvittis und Marjalahti, by Leonard Henrik Borgström.
It appears to be a very comprehensive report; if anyone has an English translation, I’d be very happy to see it…and would be glad to post it here if that might be possible.
Here’s a photo of the fall along with some other Finnish meteorites, Bjurböle and Hvittis:
This 15.3 gram end cut came from Marlin Cilz, in 2002. The photos below were taken in 2014.
