20-Oct-2015 -- Back in south western US to attend the ASA 2015 annual meeting in San Diego to present results from our team. ( www.esicm.org ). As usual I saved a few days for a touristic round trip in California, Utah and Arizona. We choose to visit the 4 CP close to our itinerary : N35 W117, N37 W113, N36 W112, N36 W111.
We visited this second on our way from Zion national park to lake Powell. It is located in the northwestern part of Colorado city and just 25 meters south of of the state line between Utah and Arizona. It is very easy to reach. The state line is materialized by Uzona avenue which runs through the city and separates a small northern part in Utah from the larger southern part of the city in Arizona. The state line is also materialized by a road sign some 50 meters south of the point on Hwy 389.
