Dresden, Saxony, Germany

What an incredible climax to all the castles, cathedrals, artwork, and amazing human-made artifacts is Dresden. Baroque, overboard, exquisite. Our last couple of days on this trip are in this often rebuilt city.

Clare went with people from the conference for half a day while Brian went with other attendees to see the Dresden Ion Beam Center. She met Marta, who kept Clare from getting lost (by stopping to gape at the incredible buildings in the city).

Clare’s group first went to the Mathematisch-Physikalischer Salon to see old clocks, globes, drafting tools, and other scientific instruments.

Later, Clare’s group went to the Green Vault to see amazing gold, silver, ivory and gemstone collections. Unfortunately, photographs were strictly forbidden. The rest of this post is when Clare and Brian were together in Dresden.

The clock struck one.
Between airplane flights, we spent the night at the Hilton in the Munich airport. We were told that these palm trees are alive and that they occupy the tallest hotel atrium in Europe. Our flight to Denver was on time and very smooth.

Stolpen Castle and Saxon Switzerland National Park, Saxony, Germany

The last day of the conference was actually a field trip to (sort of) three castles. Basalt and sandstone: the first providing the building materials for a hilltop castle and the latter providing spectacular pinnacles that long ago supported a fortress castle. The conference provided the opportunity to visit these sites in a field trip, followed by a dinner at another castle closer to Dresden.

Most visitors to Stolpen Castle are interested in the “torture” part of the displays in the castle, so our group was a bit unusual. How many tourists happily look at the rocks? Basalt seems an unusual stone to build a castle!

The fun part of wandering around a castle built of basalt was all the cool (temperature) rooms in every direction. This was important because we walked up a hill to get to the castle, and we were all hot.

We visited the lapidary area in the lowest portion of the castle, where rocks were shaped into regular hexagons and other works are done.

Saxon Switzerland National Park is a beautiful area with a castle built in the Middle Ages on top of extremely steep outcrops of sandstone. Our entire group of field trip participants climbed down the stairs and across the bridges to get to the castle ruins.

The rocks formed these columns in a similar way to the columns in Bryce Canyon NP in the US, except that the sandstones at Bryce are much softer.

Our third castle of the day was where our group had dinner together. Great food, great conversation. From there, Brian and Clare took a tram to Dresden.

Chemnitz, Saxony, Germany

Brian took a day off from the conference, and together our travelers took a train to another small town in former East Germany. Chemnitz was called Karl-Marx-Stadt beginning in the 1970s, but the people of the city voted to return to the historic name as soon as possible after the reunification of Germany in 1990.

This is simply called Red Tower.

Near the Red Tower, we met a woman also visiting, who spoke excellent English. She was from former West Germany, and lamented that her visit to this town makes her believe that Germany is still divided. The unification was only a generation ago; perhaps more time is needed.

Terra Mineralia, Freiberg, Germany

The museum in this old castle was the site of the opening reception for the Geoanalysis conference. Plenty of food and drink were arranged throughout the galleries.

The “best mineral museum in the world” is indeed fantastic. It’s organized primarily by continent. The Hall of Europe divides the minerals into chemical groups, carbonates, salts, silicates etc. This took Clare a while to figure out, because of the Covid arrows on the floor, directing visitors to take a certain path to minimize contact. The arrows, of course did not follow the chemical groupings.

Big specimens. Unbelievably big. But without scale, photographs cannot capture the awe felt by visitors to this place. Instead, Clare concentrated on showing pictures of fun or unusual minerals from these collections.

The explanations of the genesis of minerals in the Hall of Europe included pegmatite, skarn and hydrothermal veins, all environments where crystals can grow freely, forming perfect crystal faces. These large, graphic displays are all in German, no other translations.

The Hall of Africa is divided geographically and by mining region. The explanation signs, at the ends of cabinets, were translated into English (hooray) and, reading them, Clare learned a lot about the genesis of many unique ore deposits and the minerals found in each.

Display cases in each of the rooms varied a lot. All were controlled environments with good lighting, but the way minerals were displayed was different.

The Americas were combined into one room, north and south together. Clare was happy to see rhodochrosite from Alma, the official state mineral of Colorado in the same case as benitoite, California’s official state gemstone. Asia and Australia were combined into one room as well.

Scepter Quartz, or crystals dancing

Another area, not in the castle, showcased minerals of Germany. but the first room you walk into shows crystal faces in wooden models. So many times when teaching, Clare wished for such models to explain symmetry.
