Weather:  A few clouds, but nothing threatening:  Our choice this week was mostly due to the ever-decreasing amount of available sunlight.
Present were:
  Gordon, K7HFV;  Chris, KF7P;  Tim, KK7EF;  Dale, WJ7L and his son Scott;  Renee, N6STX and her husband Achim, NC6X,
and Clint, KA7OEI
Destination:  To Catherine Pass
Question(s) of the day:  "Is it OK if we just stop at the sign?"
Total distance (GPS):   About 4.92 miles - some of that from wandering around in the lake...
Times:  Departed vehicles:  1845;  Passed turnoff to Lake Dog:  1904;  Arrived at Lake Mary:  1922;  Departed Lake Mary area:  1935;  Started switchback above Lake Martha:  1944;  Arrived at Catherine Pass:  2009;  Departed Catherine Pass:  2040;  Once again at bottom of switchback above Lake Martha:  2104;  Passed Lake Mary dam:  2116;  Passed Lake Dog turnoff:  2130;  Returned to vehicles:  2149
Altitudes in feet ASL (GPS approx):  Vehicles: 8780;   Lake Dog turnoff:  9370;  Catherine Pass:  10280

Altitude gain/loss (approx.):  1500 ft.
Local sunset on this date:  2005 at an azimuth of 283
° and we have lost about 58 minutes of sunlight since the date of the latest sunset - and about 11 minutes in the past week. (The 29th of August had 13:13:37 of daylight making the day about 18 minutes shorter than a week ago. The sun was about 94.42 million miles distant.)
Total 2007 WNH mileage (if you have been on all hikes so far): 58.76 miles approx.
Total number of footsteps:  Approximately  10220 footsteps, assuming an average of about 30.5 inches/step.  This makes for a total of about 130091 steps hiked by me during the Wednesday Night Hikes during this WNH season.

Notes:
With the escalating negative increase in the lateness of the period during which suitable levels of solar illumination exists, there is the inevitable regression of the duration of the perambulatory activities through alpine regions for the dual purpose of beneficial physical exertion and mental amelioration.  In addition to that, the hikes are getting shorter because of the earlier sunsets.

After a brief discussion, we decided that Catherine Pass (via Lake Mary) was a reasonable hike for the amount of daylight that was left.  Initially, we'd considered going the "alternate" route which takes one past Lake Dog, but in consideration of some of Achim's concerns as to the route and potential knee problems, we went the more traditional (and somewhat less challenging) Lake Mary route.  As it turns out this route was probably a bit more interesting, anyway...

Piling into the cars, we proceeded up the canyon - only to be slowed by a member of a herd of cement trucks (I'd counted at least four that had gone past the parking lot before we left) - but the considerate driver was finally able, at a suitable spot, to slow down and pull to the side and let those stuck behind him go past.  As it turned out, he was going slow enough that even Dale's car was faster!

One thing that we noticed upon arriving at Brighton was that there seemed to be a lot of water flowing down from Twin Lakes.  After arriving, unloading, and hiking to the Lake Mary/Lake Dog trail junction, we were also struck that the stream below the Lake Mary dam was almost completely dry and that the wier wasn't functioning - mostly because there wasn't enough water to flow over its top.  When we got to Lake Mary, it was immediately apparent why this was so:  Although the water was still above the level of the sluice gate, that gate was closed to impound what little water was remaining in the reservoir.  I can say that in all of times that I've been to Lake Mary over the years, that I have never seen its water level as low as it was on this occasion.

Before the construction of the Lake Mary dam in 1914, there were actually two lakes - Lake Mary, the larger and lower lake, and Lake Phoebe, a smaller lake that flowed into Lake Mary.  Not having found pictures of the two lakes, I don't know the precise extent of Lake Phoebe, but it was clear that if Lake Phoebe wasn't again extant, it wouldn't take much more lowering of the water level to make it so.  Between the two apparent water bodies was a suspiciously straight channel - one that looks man made - but I can't be sure.  Because of the low water level, I took that opportunity to walk to the island and the normally-underwater channel between the two lakes and take a number of pictures that would normally require SCUBA gear.

After stopping at Lake Mary/Phoebe, we continued onwards, first past Lake Martha (which seemed to be its normal, marshy, self) and then Lake Catherine.  While the majority of the group didn't quite get to the pass before sunset (which was at 8:05 on that day) we missed it by only a few minutes - something that we had to infer from our watches, as the western clouds pretty much prevented a show of alpenglow at the appointed time.  By the time the main group arrived at the pass, Tim, Dale, and his son had taken off for higher climes.  Before too long, a lone figure, Dale, appeared on Sunset peak, soon joined by Scott while  Tim satisfied himself with a lesser goal of making it to the vicinity of the lower, unnamed peak that was on the way to Sunset Peak.  When the middle group arrived at Catherine Pass, we found Chris already there, somewhat annoyed that some old man had upped the ante past what he wanted to do...

Not too long after the majority of the group had arrived at Catherine Pass (and some of that group had moved on toward more lofty goals) we heard from Achim and Renee, apologizing for not being able to make it all the way and that they would be stopping at a sign just ahead.  We looked at each other, briefly, somewhat puzzled, but quickly realized that they meant "this" sign - the one right in front of us on the pass.  Sure enough, Renee and Achim hove into view, just a few seconds later.

In the gloaming, Dale and the others had already headed down from above, soon joining us for the obligatory group picture.  Not too long after this, everyone dug out their flashlights (although some were content to mooch photons from others) and headed down.  The descent went without incident and we soon found ourselves in the dark Brighton parking lot.

After an uneventful trip drive down the canyon (dodging a few deer, as usual) most of the group wandered home, while Tim, Gordon and I sauntered over to TGI Friday's for a dime lime.


About the Lake Mary reservoir/dam, and some of the other lakes:
The Lake Mary dam was constructed in about 1914 (with final completion in 1915) at a cost of $69,000 and is owned by the City of Salt Lake:  Although originally scheduled for completion in 1914, considerably more excavation was required at the dam site to reach suitable bedrock, causing delays in its final completion.  Materials for the dam were first taken to Park City via rail, then transported by wagon to Brighton, and then by light wagon and pack animal up to the construction site.

Lake Mary is part of a protected watershed with a capacity of approximately 600 acre-feet (about 196 million gallons) - about 2/3 that of Twin Lakes.  Lake Mary is actually two lakes, but the smaller one (Lake Phoebe) is normally merged with Lake Mary and is only visible during very low water years - like this one...

Lake Mary, originally called "Granite Lake," gets its name from New York artist Hartwig Borneman naming it after his wife in 1872.  Lake Martha was named by Alfred Lambourne, after his mother, while Lake Catherine got its name from William Brighton (yes, that Brighton) who named it after his wife, but it wasn't until after 1890 that this name came into common use.
This information about Lakes Mary, Martha and Catherine is from Charles Keller's book, The Lady in the Ore Bucket.
