Logistics

Following FOP tradition, we will keep up-front costs low by leaving participants responsible for transportation, food, campground fees, and printing of a personal hard copy of the guidebook. Each day you will need a water bottle, good hiking shoes, and your lunch.

Directions:

The trip will begin at Ponderosa Grove campground located ~7 miles southwest on Hancock Road from its junction with Highway 89 (see map 1 below). If you are camping at Coral Pink Sand Dunes State park, we will meet you at the first stop.

NOTE: if you are arriving in the area around dusk or after dark PLEASE be cautious about

deer crossing the roads on the drive down (it’s rut and hunting season so the deer are more

active). Also, note that there are black cattle at large on the final 10-20 miles of roads

heading into Coral Pink Dune / Ponderosa Grove campgrounds.

Friday, 10/14 (see map 2): Total distance for the day = 40 miles round-trip Morning: Discuss history and constraints of the Coral Pink dune field 7:45 - 8 am: The trip will begin either by meeting at the FOP group headquarters at group

site #2 at the Ponderosa Grove BLM campground (7:45 am) or at the Star Dune overlook parking lot at Coral Pink Sand Dunes State Park (8:00 am) near the campground (see map 1).

Stop 1.1: Star Dune overlook (close to the campground) - Provides a great overview of

the active portion of the dune field. Discuss modern development of the star dunes as well as the ages and implications of the stands of ponderosa to the south. Walk to the top of the Star Dune for an easy and quick hike that will give more perspective of dune-field-organization.

Stop 1.2: The cattle guard pullout (about 3/4-mile north of the main park entrance). This

stop gives easy access to an overlook from one of the limbs of some parabolic dunes that are on the western edge of the dunefield. Discuss radargrams collected from this portion of the dunefield that indicate the western edge is underlain by a series of down to the SE normal faults that were mapped by our graduate student, Janna Rozar. View the boundary of the Sevier Normal

Fault and the dunes climbing up the fault scarp towards the NE. Stop 1.3: Lunch at Ponderosa Grove Campground. This site provides access to the

marginal dunes and an overlook of the upper dune-field, its organization, and the trees that exist up there.

Afternoon: Introduce arroyos, OSL dating, and discuss history of arroyo cut-fill

dynamics in Kanab Creek

Stop 1.4: Owl’s Eyes (latitude 37.065687, longitude -112.537198) is located ~1.4 miles on right, if headed south on HWY 89 after passing the weigh station. Go over cattle grate and park on dirt lot. View Holocene alluvial stratigraphy exposed in a 40m cut-bank along Kanab Creek.

In July of 1883, Utah’s Deseret News reported on the “The Great Washout”. Masses of earth as large as common houses floated down the stream with willows still standing. Extensive damage to crops, and all farming land in the canyon was destroyed. Some cattle killed. Canyon near old city dam was cut 50 feet down and 88 yards wide.

General Itinerary:

5 | P a g e

Stop 1.5: Best Friends Stratigraphic Section (latitude 37.113860, longitude -112.548073) is located ~0.5 miles down Angel Canyon Rd from junction with HWY 89. We will park in the RV parking area at the visitor’s center and walk to the arroyo wall exposure. We will discuss the terraces and alluvial stratigraphy at this site from the overlook, then walk down to look at the alluvial sediments up close.

Saturday, 10/15 (see map 3): Total distance for the day = 85 miles round-trip

Morning: Explore upper Kanab Creek at knickpoint, discuss Grand Staircase geology, and spatial and temporal distribution of erosion rates

8:00 am: Meet at the Ponderosa Grove Campground FOP group headquarters. Stop 2.1: Upper Kanab Falls (latitude 37.291173°, longitude -112.492507°) is a 30-mile

drive from Ponderosa Grove Campground. This is the location of a small knick-point outcropping in the upper basin-fill alluvium. Holocene alluvium is preserved and exposed in arroyo walls. Background information on the geology of the Grand Staircase will be introduced. Discuss spatial and temporal variability in catchment-average erosion rates. Walk to one stratigraphic section that has been dated and described (OSL and 14C, see Townsend 2015) and sampled for Beryllium-10.

Afternoon: Explore the adjacent watershed, Johnson Wash, discuss regional fire reconstruction, hydro-climate reconstructions, and compare arroyo chronologies throughout region.

Stop 2.2: Basalt Junction (latitude 37.231783°, longitude -112.364927°) is a 16-mile drive from Stop 2.1. We will have lunch here and discuss regional climate and fire reconstructions. After lunch we will enter Johnson Wash arroyo and walk ~1-mile downstream to a series of dated stratigraphic sections where we will discuss regional arroyo chronologies and potential drivers of arroyo cut-fill dynamics.

Evening celebration and planning for next FOP at Ponderosa Grove Campground.

Sunday, 10/16 (see map 4): Total distance for the day = 70 miles one-way Morning: Discuss aggradation versus paleo-flood deposits in Buckskin Wash. 8:00 am: Meet at the Ponderosa Grove Campground FOP group headquarters. OR if

staying in Kanab we will collect you as we drive through on our way to Buckskin Wash/Wire pass.

Stop 3.1: Wire Pass Trailhead is located on House Rock Valley Road (latitude

37.019224°, longitude -112.024835°). We will walk down to the confluence of Kitchen Corral Wash and Coyote Wash and up Buckskin Wash to backwater deposits. We will shoot to get back to the vehicles at 1 or 2 pm. On a pre-trip scouting mission, Joel made the following observations at Buckskin Wash:

“Buckskin was flashing with about 4 feet deep of flowing chocolate and

standing waves. Very cool. I camped there and smelled flowing mud all

night. By morning it was down to a gentle thin stream and I crossed

without much problem.”

The trip will end around 1:00 to 2:00 pm.

Figure 5 - Processed and interpreted GPR data for Line 305 (top) and Line 200 (bottom). Top: A S-N transect that reaches from the south flank of First Dune to the base of the star dune; (A) Migrated data; (B) Migrated data with AGC applied; (C) Interpretation for Line 305 shows that First Dune is a topographic feature comprised primarily of bedrock with sand cover that is less than 5 meters thick. Bottom: A) Migrated data; (B) Migrated data with AGC applied; (C) Interpretation for Line 200 shows a series of antithetic faults that have an apparent dip of approximately 39° to the east. Bedrock outcrops in the far west part of the transect and shows the contact between the upper “white” sandstone and middle “brown” sandstone of the Navajo Formation. Fault interpretations are based on offset in the bedrock and lack of bedrock reflectors between obvious bedrock reflectors. The bedrock drops off dramatically at 900 meters; this represents the western edge of the proposed paleo-channel. The sediments filling the paleo-channel onlap the bedrock, at this point. Caption modified from Rozar, 2015.

(A) The current dune surface, based on the 5-m DEM, with 3 x vertical exaggeration. (B) The 5-m detrended surface, with 3 x vertical exaggeration, shows that the dunes are housed in a valley with a steep western side. Several scarp-like features are present, and are denoted with dotted black lines. (C) The location of scarp-like features on a Google Earth imagery show that the marginal parabolic dunes may rest on series of scarps. There is also scarp-like feature just east of the star dune and First Dune. (D) Potential fault zones were identified based on the presence of scarp-like features. GPR surveys were focused in these areas. (Rozar, 2015)

Figure 16 - Generalized terrace and fill stratigraphy for the type locality within the middle reach of the study area. Five fill packages are present and four were dated

through OSL and radiocarbon dating. In this reach Qat4 is 40 meters above the modern channel, and is underlain by Qf1. Qat2 is ~20 m above the modern channel,

and is a compound cut-fill and fill-cut (alluvial strath) terrace underlain by Qf2, Qf3, Qf4. Where unconformities are observable Qat2 is a fill-cut terrace formed by

arroyo down-cutting from the top of Qat4 halfway into Qf1 alluvium, and it is composed of Qf1 overlain by a thin veneer of Qf2. Inset into Qf1 and Qf2 under the Qat2

terrace are two cut-fill units: Qf3 and Qf4 that are of similar thickness and represent two periods of fluvial aggradation separated by incision. It is hypothesized here

that the upstream veneer of Qf2 is correlative with similar-ages alluvium dated by Smith (1990) in the basin-fill reach. Note grey beds in photographs are prominent

stratigraphic markers and are fine-grained silty clay facies (Fsm/Fsmv). Qat1 is the lowest terrace at 3 to 5 m above the modern channel and underlain, at least in part,

by the older historical fill Qah1.

Day 2 - Saturday Afternoon: Explore the adjacent watershed, Johnson Wash, compare arroyo chronologies throughout region, and discuss drivers of arroyo cut-fill chronologies.

Figure 23 - Curves represent the summed probability distributions smoothed using a 20-year moving average for Escalante River (orange), Paria River (green), Johnson Wash (blue), and Kanab Creek (red). The inverted histogram below each curve is the sample count creating the above distribution.


Figure 24 – Black curve represents the summed probability distributions smoothed using a 20-year moving average for all regional samples in the Grand Staircase. Red triangles identify multi-basin fires defined by statistically similar radiocarbon dated fires from two or more watersheds. The top three data sets are hyrdro-climate reconstructions derived from tree-rings.


Figure 25 - Map of stratigraphic sites in Johnson Wash used to make arroyo chronology.


Figure 26 - Stratigraphic section from Johnson Wash. Radiocarbon ages in blue text are age-over-estimates. OSL ages in yellow and green text are age reversals.


Figure 27 - Regional arroyo cut-fill chronology in comparison with regional hydroclimatic records. Note there appears to be a relationship between arroyo entrenchment and periods of drought followed by pluvial conditions (dry to wet). The two most extreme droughts in the last 1ka appear to correspond with the two most recent arroyo entrenchment events. Note that the drought/pluvial couplet ~400 yr ago did not cause arroyo entrenchment. Rittenour (2016).


Figure 28 - Conceptual diagram illustrating the idea that while floods are necessary to drive arroyo entrenchment, that geomorphic thresholds related to long profile slope (concavity) may be the ultimate driver of when streams entrench. Aggradation rates are linked to sediment supply and valley geometry.

- Timing of arroyo entrenchment may be controlled by geomorphic variables controlling grate of aggradation and when slope/concavity

thresholds are approached.

- After the system approaches a threshold slope, a sufficiently large discharge event can lead to arroyo entrenchment.

- Note that the system may not be sensitive to similar or even larger magnitude floods when not near a threshold.


Figure 29 - Examples of ubiquitous soils capped by more recent (post 200 yr) alluvium seen in the study

catchments. The exact age of these soils and overlying alluvium is not yet known, but results suggest

the overlying alluvium is < 200 yr old and may suggest that it could be associated with post-settlement

alluvium related to over grazing and forest clearing practices.

Day 3 - Sunday Morning: Discuss aggradation versus paleo-flood deposits in Buckskin Wash.

Figure 30 - Map of Buckskin Wash study area showing primary sites and geographic features. UT-Utah.

Circles are optically stimulated luminescence ages, triangles are 14C ages (clack – from correlative unit away from main outcrop), and squares are 137Cs samples (open where absent; filled where detected). The entire site is interpreted as channel margin deposits.
