Keystone: This geocache came to my attention as being in need of an owner maintenance visit. The cache owner needs to check on this cache ASAP and either fix the problem or archive the listing, after picking up any geo-litter. See the maintenance section of the Geocache Hiding Guidelines. In the meantime, I've temporarily disabled this cache page.

Owner, if there is a good reason for a long delay in enabling this cache, do not contact me through email or the message center. Please post an update note log here on the cache page so that everyone will know what's going on. When the maintenance is completed, you can re-enable the listing by entering an "enable listing" log. Use an "Owner Maintenance" log to clear the "Needs Maintenance" attribute, if set.

I will check back in four weeks or so to be sure that the maintenance has been done, or that an explanation has been provided. If the problem persists, I will need to archive this cache page for lack of maintenance.

Regards,

Geocache Description:

This cache is one in an ongoing series highlighting important figures in the history of the academic discipline of geography. If you complete this series, you might be ready to pass your qualifiying exams for a PhD in Geography!

Torsten Hägerstrand (1916-2004) was a Swedish geographer who did important work in cultural geography. He was an important figure in the "quantitative revoltion," pushing for the use of mathematical techniques in geographical research. He emphasized the importance of examining individual behavior in order to understand social phenomena, and of linking human behavior to spatial location. His best-known contribution was the concept of "time-geography," in which the activities of a person are traced through the course of a day or lifetime to show where they traveled and how much time they spent in one location or another. Time-geography is often illustrated with a three-dimensional diagram like the one shown below.
