I visited Zion NP last week. The weather was much nicer than I expected; mostly sunny with highs in the mid 60s. I stayed at my favorite hotel, the Cliffrose Lodge, where the pool and hot tub were still open. I didn't see any others open when I drove through town. I like the Cliffrose because the staff are always happy, friendly and helpful.
I decided to visit the "secret" petroglyph site to take some photos. I figured I could have the place to myself at this time of year. This is the worst-kept secret site at Zion. But I'll fulfill my obligation by not sharing its exact location. Hint: it's in Petroglyph Canyon (aka Pictograph Canyon). The site is a 5 minute walk from a large parking turnout.
