Oil has been drawn through the narrow spaces in the boardwalk by heat,
leaving a gross, sticky tar as sealant.  The boards extend from the edge of
the oil pool that made the tar, out to the edge of the road several meters
away.  While there are guardrails that prevent passage west directly into
the pool, it looks like there are some loose boards in the walk that could
be pried up.  The boardwalk continues around the pool.
