PROBLEM: Passage: The 200th anniversary of the Finnish War was recently selected as the main motif for a high value commemorative coin, the €100 200th Anniversary of Finnish War commemorative coin, minted in 2008. The motif on the coin is the passage from Sweden to Russia. The same coin depicts both Finnish history, with the withdrawing crown on the reverse side as well as the future of the country, with the eagle symbol on the obverse side. In memory of the 200th anniversary of the Finnish War, all Swedish 1 krona coins minted during 2009 featured a stylised depiction of the sky and the sea on the reverse side, flanked by a quote by Anton Rosell: Den underbara sagan om ett land på andra sidan hafvet .

PROBLEM: Passage: Trying to snap a four-game skid, the Ravens flew to Qualcomm Stadium for a Week 12 duel with the San Diego Chargers.  After a scoreless first quarter, Baltimore trailed as Chargers kicker Nate Kaeding managed to get a 27-yard field goal.  The Ravens would take the lead with RB Willis McGahee getting a 1-yard TD run. San Diego retook the lead with QB Philip Rivers completing a 35-yard TD pass to TE Antonio Gates (with a failed PAT), Kaeding kicking a 46-yard field goal, Rivers completing a 5-yard TD pass to WR Chris Chambers, and Kaeding kicking a 41-yard field goal. In the third quarter, Baltimore's struggles continued as Rivers and Gates hooked up with each other again on a 25-yard TD pass.  The Ravens' QB Kyle Boller completed a 13-yard TD pass to rookie FB Le'Ron McClain.  In the fourth quarter, the Chargers sealed the win with Kaeding nailing a 41-yard field goal. With the loss, not only did Baltimore fall to 4-7, but it marked the first time in franchise history that the Ravens had lost five straight games.

Of the remaining Colorado streams, 122 (2.2%) were named arroyo (creek), 60 (1.1%) were named wash (creek), 44 (0.8%) were named stream, 18 (0.3%) were named stream, 17 (0.3%) were named stream, 17 (0.3%) were named stream, 15 (0.3%) were named stream, 10 (0.2%) were named River delta, but not a single stream was named stream.
