This cross is locally known as "Kleines Engländerdenkmal", literally "Little Memorial to the English". It bears a German inscription on the mountain side, and an equivalent English inscription on the valley side. Eaton intended to add the line, "Their teacher failed them in the hour of trial", but this was disallowed, as the official version of the event exonerated the teacher. On the Schauinsland, there is a solar telescope, which is operated by the Kiepenheuer Institute for Solar Physics, which nowadays is only used for teaching and PR. Current research is mostly done at the Observatorio del Teide on Tenerife. The observatory can be visited without pre-booking on five open days between May and September, each of which is scheduled at the beginning of the year. On those days guided tours take place between 11 A.M and 3 P.M. The observatory was founded in 1943 by the German Luftwaffe of the Third Reich to make the most accurate prediction of the ideal frequency for military radio communication by observing the solar activities. It was managed by Karl-Otto Kiepenheuer from 1943 until 1975. There is also an air measuring station on Schauinsland which belongs to the German and the . The concentration of air pollutants is measured as part of the European Monitoring and Evaluation Program (EMEP), the climate-relevant gasses and radionuclides are recorded as part of the GAW. Both this building and the solar telescope were built in 1943 and were used to observe the quality of the ionosphere for the purpose of military radio communication. A measuring station for the permanent monitoring of the artificial and natural radioactivity in the atmosphere has existed on the Schauinsland since 1957. It was integrated into the newly founded federal agency for radiation protection in 1989. Among other devices to measure traces of radioactivity in the air, the "Ortsdosisleistungs-Messnetz" and the supervision of the adherence to the Comprehensive Nuclear-Test-Ban Treaty (CTBT) takes place there. The Schauinsland is a very popular area for Freiburg and the region as it is suitable for a number of outdoor adventurous activities including hiking, skiing and mountain biking. In the winter, sledging is possible on the Holzschlägermatte or on the higher areas of the mountain where a sledge-lift operates. Cyclists can visit the Schauinsland for both challenging and leisurely trails and use the Schauinslandbahn to help them ascend the mountain.
