Black Mountain Open Space Park was the site for SDMBA's
February 5, 2011 Trails Work day. Site of a defunct arsenic mine that went
belly-up in the 20's, the Miner's Ridge Loop trail itself is in fine health
these days thanks to the 33 volunteers who forfeited part of their Super Bowl
weekend to give a little back to the most popular trail on the mountain.
SDMBA liaison to the park, Rod Simmons was joined by fellow
skilled trail bosses, SDMBA president Gardner Grady, Mike MacGregor, Andy
Darragh, Bryan Furbee, Brian Nixon, Rich Julien and Sr Park Ranger Ed
Christensen in mentoring the days volunteer work force.
|
As with all SDMBA trail events, the day started with workers signing
liability releases which also double as entry forms into the days drawing
for prizes donated by the event's sponsor.
Black Mountain Bicycles donated
merchandise and gift certificates awarded following the completion of
work.
Badass Coffee was
available to those who's day just cannot start without a caffeine
jolt.
Following the always informative safety briefing, workers assembled to
select the tools they'd be using for the day. Choices, choices . . . |
The
focus of work on the Miner's Ridge Loop was threefold.
1. Repair damage caused through usage and more significantly, damage
caused by water erosion.
2. Repair rock bars and and water diversion features so that water from
future rain storms is routed off the trail prevented new erosion from
occurring.
3. With the trail tread repaired, speed differential between user
groups would likely be increased causing user conflict. Chokes and other
techniques were deployed to regulate speeds while enhancing trail
experience.
|
Safety is of utmost importance. The trail will be here tomorrow and we
strive to make sure our precious volunteers are too. Here SDMBA president
Gardner Grady graphically illustrates the "circle of death"
available when wielding a pick/mattock. The pick/mattock is the tool of
choice for excavating the concrete like soils we have here in San Diego.
It's ability to penetrate hard ground also make it a potentially dangerous
tool when used in close proximity to other trail workers. Our workers are
briefed to be aware of not only the "circle of death" for their
tools but also to remain alert and not stray in the "circle of
death" of another worker.
Garner's hardhat makes him the most visually recognizable SDMBA-ite at
trail work events. Grant requests are currently being submitted so that we
can fund equipping the hardhat with a propeller for the 2012 trail work
season.

All
trouble spots on the trail had been previously flagged by SDMBA liaison
Rod Simmons.
Blue designated the need for new water diversion features, yellow for
rock work (chiefly repair of blown out rock bars), and red for tread
repair (deberming and outsloping).
Thanks to the stellar turnout all flagged work was accomplished ahead
of schedule. The work parties were then dispatched to switchback section
of trail to enhance the emergency drains created during December's
prolonged downpour.
|
Following
the completion of work the team relocated to the nearby Black Mountain
Ranch Community Park for a post-work BBQ.
Stone Brewing Co.
generously donated 5 gallons of Pale Ale that was universally appreciated
by the parched workers.
The prize drawing was held with the big winner being Bryan Furbee who
landed the $50 gift certificate from Black
Mountain Bicycles
|
Joining
us for the BBQ were Sr Ranger Ed Christensen (who could only look on
forlornly as we availed ourselves of the Stone Pale) and Friends of
Penasquitos representative to the Black Mountain CAC Mike Kelly (seen here
in the green hat).
The Friends had a concurrent workday planting cactus in the Lusardi
creek area as part of an effort to bolster the nesting range for the
endangered cactus wren.
Past cactus wren plantings have been attended by SDMBA board members
Rich Julien, Russ Boggs, SDMBA liaison Rod Simmons and past SDMBA
president Minette Ozaki.
