|Last fond look at the Research Station.|
|Our ride awaits.|
|Well, uh, not as well as we thought. We got to about the nicest view point on the highway and the bus started having cooling problems.|
|The distant peak is the high point of Carara National Park.|
|Left: The problem turned out not to be too serious.

|Turrialba, 3,340 m (10,958 ft) gave us the most convincing display of volcanic activity with this persistent steam plume. Turrialba had a number of eruptions in the 19th century and began showing increased activity in 2001.|
|Volcan Barva (2906 m; 9,534 feet) is the least active of the three major volcanoes overlooking San Jose. It last erupted about 6000 BC|
|Wisconsinites are used to seeing large screens like these used for growing ginseng. Here they are used for shading flowers.|
|Poas is a popular outing spot and we inched our way in.|
|Irazu, 3,432 metres (11,260 ft) is the peak beyond the clouds. It's
the highest active volcano in Costa Rica and, apart from a steam blast
in 1994, last erupted in 1963-65. The flank of Volcan Barva is in the
Unlike Hilary Clinton, John F. Kennedy really did land under fire. The 1963 eruption began the day he arrived for a state visit.
Irazu has had more than 20 explosive eruptions since 1723.
|This little bowl is a former crater of Poas.|
|The devegetated area is probably from eruptions in the spring and
summer of 1994.
Good news: we had a crystal clear day, unlike the visit in 2007 where the crater was socked in.
Bad news: we missed a small steam explosion by just a couple of hours.
|Below: ejecta layers near the crater.|
|The trail leads to a lake in an older crater of Poas. Increased thermal activity in the lake led to trail closure for safety.|
|Below: the low area is an inactive crater of Poas.|
|Views of San Jose on the way down.|
|We didn't eat at the Low Stress Zone but at an only slightly higher stress restaurant nearby.|
