We then headed to see the Grand Prismatic Spring at Midway geyser basin because Brian remembers seeing a huge colorful pool when we was a kid. The parking lots in these areas are a joke. Passengers get out of their cars before pulling in to the parking lot and then go wait for someone to leave and stand in the spot until their car arrives. We got stuck in this parking lot for 20 minutes just waiting behind people one day so Brian decided to park along the road so we didn't waste another 20 minutes trying to park.
I loved all the colors in this geyser basin. Grand Prismatic Spring was all steam covered so you could barely see the vibrant colors. But there were colors elsewhere and interesting patterns.
After that we headed to Norris geyser basin where Steamboat geyser is. We couldn't do the small loop because they were building new boardwalk so we skipped the small loop. We decided to do the 2.6 mile loop but we were also trying to stay ahead of thunderstorm so we walked very quickly. Luckily there wasn't too much to see. Most of the pools were not so pretty and the geysers weren't doing anything. I think you could skip Norris geyser basin.
This is Emerald Spring
This is the most action we saw at Norris
We then drove up to see the terraces at Mammoth. It poured rain the entire drive and entire time we were at the hot springs plus all the way back to our campground. I think this was the day it rained for the longest period of time. We did avoid the thunderstorm at Norris though! The terraces were so disappointing. Mom and Dad told me that they had changed but I didn't anticipate hardly finding any terraces at all!
Here is one terrace starting to form
