When our species has become extinct, is there anything that would survive long enough to tell the next intelligent species to arise that we were a technological civilization?

There will be strangely distributed concentrations of various materials in any sediment layer from our period, such as iron, copper, aluminum, hydrocarbons, and various minerals. A lot of these will be in relatively small areas and also laid out in clearly artificial geometric patterns, especially in straight lines.
