SunZia, Buehman Canyon to Brush Corral Road – 1/8/2018, 1/16/2018, 2/25/2018, 2/26/2018

(This is Part Two of a series of Posts on the SunZia Transmission Line Project – the previous post was SunZia – Redington Road North to Buehman Canyon – 12/12/2017. See the bottom of either post for more information about SunZia.)

The rocks look like maps – they remind me of the shape of the San Pedro River and of the brutal line that the SunZia project may cut thru this landscape. On four different days I explored the canyons under, and terrain around, the proposed SunZia route – from the north edge of Buehman Canyon, across the hills to Edgar Canyon and up to the Brush Corral Road.

Recent rains must have filled Buehman Canyon with water – there is wall to wall slippery mud and debris pressed against the tree trunks. I suppose the power lines hanging overhead won’t change the canyon much, but there is an infinite difference between nothing and something.

Sitting on the south side of the Buehman Canyon the first stars of the evening appear over the SunZia route – towers on the canyon sides may eventually carry the transmission lines across Buehman Canyon – man-made shapes added to the dark silhouette of land below the stars.

Early in the morning the milky way is low in the sky and frost covers my gear, a cold start quickly changes to a warm day hiking north thru the desert. The SunZia route crosses the Brush Corral Road and continues across hills and small washes towards Edgar Canyon, both the Santa Catalinas and Galiuros are visible. A long set of access roads will be cut into these hills to construct and maintain the lines.

The lower section of Edgar Canyon is a surprise, more to explore, and more reason to come back, than I had guessed – like Buehman Canyon there aren’t towers or new access roads in the canyon bottom – ‘just’ a line imprisoning the sky. From the edge of Edgar Canyon the line follows hills and washes to the Davis Mesa Road.

It is sad to think about the changes coming to this landscape – I read Chris Townsend’s Thoughts on the Conservation and Restoration of Nature in Scotland while working on images for this post and found it encouraging and relevant – I am not familiar with the places and organizations in his post, but I suspect the subject will be immediately familiar regardless of your location:

Whilst the Gleann nam Fiadh track is depressing there is much that is positive in the conservation and restoration of nature in the Scottish hills and elsewhere in Britain. Not enough certainly but looking at what is being done can counter the feelings of despair when more damage occurs. It can also encourage a desire to help protect what is left and restore what we can. Public pressure is what counts here. I doubt many politicians would do much without it (there are a few who would, perhaps). It’s easy to think that one person can’t do anything and that signing petitions, sharing and commenting on posts on social media, and writing to representatives achieves nothing. However any effect from these actions is cumulative. If enough people take part then sometimes a momentum can build towards something happening. The alternative is to give up.

Point 7556 Near the Knagge Trail – 2/4/2018

Point 7556 is a short distance from the Knagge Trail – no trail, but easy enough to get to. I can’t remember having walked out to it before, no idea why not, but I guess with so many places to explore…

In a way it might be better that I overlooked it until now. Years ago the views would have been just as spectacular – a sweeping view down into the San Pedro River Valley and across to distant mountain ranges, east side canyons and rolling hills folding the landscape – but looking down now, after having spent more time in recent years exploring the east side of the Santa Catalina Mountains, is more interesting, and more personal, than it used to be.

Knagge Trail – 2/15/2018

Clouds cover the mountain, small waterfalls decorate highway road cuts and on the trail every small drainage is flowing – the variety on the mountain is infinite, what an interesting day to be on the Knagge ‘Trail’!

The Knagge Trail is still drawn onto maps of Santa Catalina Mountains, but like the Davis Spring and Brush Corral Trails, it disappears long before reaching it’s eastern terminus. You can, of course, still make your way down to the junction of the Knagge Trail and the Davis Spring Trail in Edgar Canyon, and even find occasional convincing pieces of old trails, but at this point it is an off-trail adventure.

From Look to the Mountains, p. 69:

In addition to their homestead and the pack train, The Knagges worked a mining claim in the Catalinas. It was located on the east side of Kellogg Mountain. From around 1916 into the 1930’s, the family spent time at the claim during the summer under very rustic conditions. A simple cabin provided shelter and a spring supplied them with fresh water. On occasion, a mountain lion stalked the camp, lured by their horses and burros.

After a largely dry and storm free winter it was a privilege to spend a week under grey skies! Rain, flowing washes, road cuts turned into waterfalls, canyons filled with water – a real joy, and as I write this it looks like we might get another short storm in February!

2018 Pusch Ridge Wilderness Closure, Bighorn Sheep – 1/12/2018

The top section of the Temporary Area Closure for the Protection of Desert Bighorn Sheep signed in October of 2017. October 2017.
The top section of the Temporary Area Closure for the Protection of Desert Bighorn Sheep signed in October of 2017. October 2017.

In October of 2017 Kerwin S. Dewberry, Forest Supervisor of Coronado National Forest, renewed the Temporary Closure Order for the Protection of Desert Bighorn Sheep. The closure imposes restrictions a number of restrictions in the Bighorn Sheep Management Area of the Pusch Ridge Wilderness. The closure has been in place since 1996 and the new closure order has two changes from the past few years:

  • The closure order runs for 2 years (rather than the 1 year duration of orders since 2013)
  • There is an added restriction on domestic goats and sheep (I believe the concern is that goats and domestic sheep can carry diseases that bighorn sheep are vulnerable to).

 

See this link for more details including a map and list of trails impacted by the closure (the Bighorn Sheep Management Area does not cover the entire wilderness area) – the restrictions:

  • From January 1 to April 30 travel more than 400′ off of designated Forest Service Trails is prohibited
  • Dogs are prohibited except for seeing-eye dogs and handi-dogs – year round
  • Bring in, possess, or allow domestic sheep or goats into the closure area – year round
  • Maximum group size – day use size of 15 and overnight group size of 6 – year round

 

There were two new publications specifically about bighorn sheep in the Santa Catalina Mountains in 2017:

 

Examining the Response of Desert Bighorn Sheep to Backcountry Visitor Use in the Pusch Ridge Wilderness Area

In March of 2017 there were a number of presentations about bighorn sheep at the Westward Look Wyndham Grand Resort and Spa – if you attended you may have listened to Brett Blum talk about tracking human visitation via cameras and making detailed observations of bighorn behaviors. This research is presented in Examining the Response of Desert Bighorn Sheep to Backcountry Visitor Use in the Pusch Ridge Wilderness Area. Two interesting details from the paper:

  • “bighorn responded to increased human activity by bedding. Bedding likely decreases the potential for both detection or interaction with humans and would be a more energetically conservative approach to avoidance that may be exhibited in part due the predictable nature of concentrated visitor use on established trails.” (p. 27)
  • “A study of the former population of bighorn sheep by Schoenecker and Krausman (2002) found 18% of visitors observed engaged in off trail use between 1994 and 1996. In contrast we documented roughly 1.5% off trail use from January 2015-May 2016 suggesting current human use of the PRWA may be largely confined to established trails” … “We speculate that the effects of urbanization around the PRWA may have also inadvertently restricted visitor use to established trails by limiting non designated access points around the base of the study area that were present during the former population.” (p. 28)

Not currently included with the paper is a detailed analysis of the visitation data, Brett indicated in an email that he is “still working with the Coronado National Forest to quantify all the visitor use data” – hopefully this data will be available at a later date!

And Then There Were None: The Demise of Desert Bighorn Sheep in the Pusch Ridge Wilderness

Paul R. Krausman has worked on Bighorn Sheep research in the Santa Catalina Mountains for many years and in this book he brings together a wide variety of scientific and historic information about the sheep in the Pusch Ridge Wilderness. I think it is fair to say that the book is written for a professional/academic audience – but it is certainly accessible enough to be interesting to someone like me without a wildlife related degree. Two excerpts that might inspire you to read more:

  • “there is no evidence that predation, limited water, disease, or the presence of other ungulates contributed to the demise of the desert bighorn sheep in the Pusch Ridge Wilderness. However, the increasing human population from Tucson and surrounding areas encroaching on bighorn sheep habit, and related urbanization, have not been positive influences… there is strong evidence that urbanization and habitat alteration were major influences in their extinction” (pp. 141-142)
  • “when bighorn sheep are translocated back into the Santa Catalina Mountains, they will likely continue to need assistance from humans, including predator control, prescribed fires, periodic transplants to enhance genetic diversity and mitigate the loss of corridors to other mountain ranges, and restrictions on humans in their habitat” (p. 157)
