From Hite across the Henry Mountains
Sections 4 and 5 on the route page connect Hite to the Burr Trail in Capitol Reef. Section 4 is 35.8 miles, from Hite to the end of Poison Springs Canyon at Utah Highway 95. Section 5 is 48.9 miles, from there over Mount Ellen's South Summit to the top of the Burr Trail switchbacks. The route page's spelling is Poison Springs. The maps page's link text drops the s and says Poison Spring Canyon.
Both sections sit under the same warning as the rest of the route page. The 11,419-foot figure in that warning is this stretch: atop Mount Ellen's South Summit.
Section 4, Hite to Highway 95
The route leaves Hite by the Flint Trail, then climbs onto the red benches through a chimney route in the west fork of Rock Canyon. It loosely follows the Chinese Trail across the Red Benches, drops steeply into Fiddler Cove Canyon, and follows that canyon to its confluence with the Dirty Devil River. It goes up the Dirty Devil to the mouth of Poison Springs Canyon, follows the canyon up, and ends where the route crosses Utah Highway 95. The permit line names Glen Canyon National Recreation Area.
Choi's April 2008 note on this section says that once the way off the rim into Fiddler Cove is found, a walker should veer to the left side of the debris field, because the scree near the pinnacles ends in a short drop. His water line for the section says there was good water at a piped masonry spring. That is the April 2008 note, mile 27.1 in his numbering. The route page does not mention the spring.
The gallery captions the Dirty Devil River as one of its frames, without a date and without a flow. The caption is not the water note, and the water note is not a caption.
Section 5, and the high point the warning names
Section 5 continues the climb of the Henry Mountains on old dirt roads and eventually climbs the ridge to Mount Ellen's South Summit. From there it descends to Tarantula Mesa, then Swap Mesa, and bottoms out at the base of the Burr Trail in the Waterpocket Fold of Capitol Reef National Park. The section ends up the switchbacks of the Burr Trail. The permit line names Capitol Reef National Park. The mileage is 48.9.
The route page's opening warning uses this summit for the top of the route's elevation range: 11,419 feet. The bottom of that range, 1,800 feet, is placed in the Grand Canyon, many sections later. The page does not print the elevation of Hite, of Highway 95, or of the Burr Trail itself.
The gallery captions moonrise over the Henry Mountains, credited in the gallery's run of Brian Frankle photographs, and a separate frame of Mount Ellen. Those are the pictures the site attached to this part of the country. They are not a route sketch of the ridge.
What the 2008 note adds on section 5, and what it does not
Choi's notes for section 5 include a navigation line at mile 4.9: heading south-southwest from a T-junction leads to the lip of a 100-foot drop above Butler Wash, so he describes dropping into the small drainage in front of the junction and following it until it feeds a lower part of Butler. He also describes contouring around side drainages to get past a second pour-off and back to the bottom of Sweetwater Creek.
His water lines on that section say Crescent Creek had good water, Sweetwater Creek had a small creek of snowmelt that disappeared at a road, and there was a creek on Swap Mesa. He calls a spot in Swap Mesa a manky mudhole. Those words are his note's. They are not rewritten here as a description of the mesa now, and they are not a reason to treat meltwater as a plan.
The updates note is where those dates stay attached to the springs. This page only marks which section they belong to.
Highway 95 and the Burr Trail as the page uses them
Highway 95 is the end of section 4, a crossing, not a town description. The Burr Trail is both the end of section 5 and the start of section 6. Section 6 leaves it down Lower Muley Twist toward Hall's Creek. The Escalante note starts at that handoff.
The permit change is as sharp as the page makes it. Section 4 names Glen Canyon National Recreation Area. Section 5 names Capitol Reef National Park. Section 6 will name both, plus Grand Staircase-Escalante National Monument. The route page does not explain the paperwork. The links page points at Capitol Reef and at Glen Canyon for the agencies' own sites.
The previous note ends at Hite, which is this section's start. The Flint Trail is the first proper name of section 4 after that handoff. The page does not describe the grade of the Flint Trail or the condition of the chimney in Rock Canyon beyond naming them. Lower Muley Twist is the first canyon after the switchbacks, and it belongs to the next section, not to Mount Ellen.
Maps, captions, and the limit of both
The maps page lists section 4 as Hite to Poison Spring Canyon, and section 5 as that canyon to the Burr Trail in Capitol Reef. The overview drawings those links call for are not being served. The route text above is what remains.
A reader who came for the 11,419-foot figure has it in two places: the warning at the top of the route page, and the section 5 sentence about the ridge to Mount Ellen's South Summit. The page does not print a view description from the summit. The gallery's Henry Mountains frames are the pictures. The warning's point is the elevation and the difficulty, not a scenic stop.
The mileage table puts 35.8 and 48.9 beside the longer Escalante and Kaiparowits sections that follow. Neither Henry Mountains section is the longest on the page. The warning does not rank them as easier for being shorter. The gallery's Mount Ellen frame and the moonrise over the Henry Mountains are the pictures. They do not show the chimney in Rock Canyon.
Questions
Where does the route page put 11,419 feet?
Atop Mount Ellen's South Summit, in the warning and again in section 5, on the ridge climb in the Henry Mountains. The 1,800-foot figure in the same warning is in the Grand Canyon, not here.
What is the difference in the canyon's name?
The route page writes Poison Springs Canyon. The maps page's link text writes Poison Spring Canyon. Both point at the section that ends at the Highway 95 crossing.
What did the April 2008 note say at Fiddler Cove?
Veer to the left side of the debris field, because the scree near the pinnacles ends in a short drop. The same note reported good water at a piped masonry spring. That report is dated April 2008.
