Grand Prismatic Spring

We walked for an hour in the hot midday sun only to discover we couldn't access the spring from this walkway.  We then climbed a steep hill covered in pine trees (and I saw bear footprints!) to take an aerial shot.  When we drove on to the proper boardwalk, the parking area was not only full but jammed with cars waiting for spaces.  We decided to park back along the road and walk.  But it was worth it.

We wouldn't have seen this if we had been able to find a park.
