Crystal Palace (cave) lies high above the valley floor and yields stunning views looking northwest over Grottedalen. Collecting calcite samples from this cave was one of the main objectives of the expedition. In 2015, we discovered several thick flowstone sequences that we couldn’t sample at the time due to a lack of resources. In 2019, we returned with coring and grinding equipment (courtesy of @hiltiaustria). These tools were invaluable as they allowed us to cut large sequences down to more manageable size pieces. This meant we only took from the cave what we needed. We were also careful to sample from naturally broken material, where possible. Here, Chris is grinding a sample down into smaller pieces, whilst Gina and Paul are examining a potential sample to assess its suitability for palaeoclimate work.
