Flight by Adria Airways and Lufthansa from Ljubljana to Denver. First flight was fine. A four hour wait at Frankfurt. Then Lufthansa service to Denver was shortcoming the expectations. Boeing 747 didn’t have personal entertainment systems (yes we are spoiled...), we weren’t allocated seats together, and to top it off the plane broke down on the runway just before take off! Eventually all got sorted and after some 10 hours we arrived at Denver, at 4 PM local time. Formalities were fine and got the car we were after: Dodge Stratus, of a lovely silver shade.  Spend the Tuesday evening in Cheyenne in Wyoming.

A long drive up north to Buffalo and east to Devils Tower NM. This is an interesting rock formation of crystalline rock formed in the neck of a volcano and became exposed after years of erosion. A rather long drive to see it though. If u are there recommend to continue further east into North Dakota and see the four presidents .... it's like 150 miles away from DT NM.

Interesting note on driving in Wyoming. Apparently winds can get sooo bad that interstates close. We saw barriers on the inntersates all over the state. Got this photo from funpic to illustrate:

Fortunately on Wednesday the weather was just awesome: sunny and over 110 F. Then after Devils tower headed back east and north, through Sheridan up to Billings in Montana for a sleepover. A very long day in the office (car that is). Have done over 700 miles. Spend 55 USD on fuel, so not too bad.

Arrived in Yellowstone NP through the north entrance from Montana. Although the mileage is greater than from east entrance through Wyoming, having an interstate up to the entrance cuts the drive time.

Mammoth Hot Springs: Geothermal activities are evident throughout the park. Right up near the north entrance these activities have formed a series of terraces of steamy water, which cools and deposits minerals and metals, giving the terraces a distinct whitish look with shades of colors representing various minerals. 

After a sound night sleep at West Yellowstone, at 7 AM we headed back into the park. First port of call were the Fountain Paint pots, comprising lots of geysers of various intensity and colour and noise. Plenty of steam here too that early in the morning.

Next was the drive along the Firehole lake, followed by a dip in the Firehole river. Highly recommended and very popular. Even at 9 AM the water was pleasant, although the currents are very strong..

Next towards the Old Faithful we stopped at several basins with geysers. The midway geyser basin offered some of the most beautiful geysers.

In the afternoon headed to the West thumb and the adjacent geyser basin next to the lake. Another lot of beautifully shaped basins, some of them in the lake, some of them very colorful. The water in the gazers is soo crystal clear and blue and very inviting for a hot tub. J Temperatures are around 75C.

Finally headed out at the east entrance and after some searching found a place top crash at Cody.

Overall impression; Yellowstone is the best park we’ve seen so far and even better than all the others put together. U got everything here: water, sun, nature, hikes, swimming, rafting, sightseeing, etc etc. The climate is nice too and the provisions of everything (food, gas, lodging) are plentiful for a reasonable price. The park is big and two days are really minimum to see the key sights. Highly recommended park to visit, although somewhat remote from the other sites and cities.

Drive back through Wyoming to Denver. In the morning a brief stop over at the Bufallo Bill museum:

Next stop was at Thermopolis to see the world largest mineral spring and the Dinosaur museum.
