**Notes:**
South facing slope, Los Alamos Canyon.  These perched boulders are in a steep gully that drains into the canyon just  below the Los Alamos reservoir. Large boulder has shifted gully erosion to the right, where fewer rocks block channel. Note shadow created by boulder’s overhang of steep gradient.  Image taken August 2001.

## Slide 2

**Notes:**
Successful example of aerial seeding.  Moderate to severely burned north-facing slope of Guaje Canyon.  Image taken May 2001, one year after fire.

## Slide 3

**Notes:**
Aspen successfully regenerating immediately south of forest road to American Springs. Image taken May 2001.  

## Slide 4

**Notes:**
South Pueblo Canyon watershed; greening of area re-seeded and straw- mulched during the first week of July 2001.  Straw in background was applied in early August.  Note peeling of charred bark, which enhances insect access to dead wood.  Image taken August 2001.

## Slide 5

**Notes:**
South Pueblo Canyon Watershed near Quemazon water tank.  Typical of shallow soil unit where soil has washed away since fire.  Note extensive areas of bare rock and limited regrowth of vegetation despite aerial reseeding.  Image taken mid-August 2001.

## Slide 6

**Notes:**
Aerial view of south part of Pueblo Canyon watershed, with Pipeline Road at upper left.  Note extent of straw mulch treatments (yellow patches).  Straw in immediate foreground is successful July 2000 treatments north of Camp May Road, showing greening among burned trees. In background are north and west parts of Los Alamos, with Pueblo School visible as the white, L-shaped buildings at right. Enlargement shows burned neighborhoods, cleaned of debris, at left. Image taken August 31, 2001.

## Slide 7

**Notes:**
Aerial view of School Canyon straw mulching, lower center, completed near end of August 2001. Note mulching (faint yellow) in North Pueblo watershed in the left mid-distance, and successful mulching (green) along the Mitchell Trail at bottom right center of the photo. “LA” marker, composed of aligned white-painted boulders, is faintly visible on mountainside in left foreground. Lodge and ski runs of Pajarito Mtn. Ski Area are at upper left. Bulldozed lots and rebuilding in burned neighborhood are visible in enlargement at bottom center. Image taken August 31, 2001. 

## Slide 8

**Notes:**
Successful aerial hydromulching on severely burned, steep, north-facing slope of Los Alamos Canyon, evident in mid-distance. Effective ground cover = 35%. Note unburned ski runs at upper right on Pajarito Mountain. Pueblo Canyon watershed treatments are in foreground. August 31, 2001. 

## Slide 9

**Notes:**
Strong, turbulent storm flow under NM Route 501 at Two Mile Canyon, August 9th, 2001. Drainage bottom and lopes have been armored to reduce erosion.

## Slide 10

**Notes:**
County Ice-skating Rink in Los Alamos Canyon just after peak streamflow of August 9, 2001.  Note water and debris on road in foreground, and full creek at right. Flooded parking lot behind is draining into creek, indicating water came from upstream (right) of this spot. 

## Slide 11

**Notes:**
March 2002 aerial re-seeding (note very faint, brownish haze streaming leftward from helicopter-carried bucket).  North Pueblo Canyon Watershed.

## Slide 12

**Notes:**
Newly developing gully draining into the southeast corner of Los Alamos Reservoir.  It has breached a lakeside trail’s retaining wall. Gully was initiated by road runoff from high intensity rainstorm of July 2, 2001.  White at left is concrete foundation of dam, with straight line marking top of sediment that has filled reservoir due to heavy upstream erosion in Los Alamos Canyon.  Image taken August 2001.

## Slide 13

**Notes:**
Same gully at Los Alamos Reservoir in April 2002.  Note recently fallen tree, widened gully, and less undergrowth than in previous photo.  Brown foliage of tree at right center, fully green in previous image, may show effect of reservoir’s having dried out.  Note dam foundation at left, excavated during re-deepening of reservoir to hold future runoff.

## Slide 14

**Notes:**
Successful aerial re-seeding treatment in Los Alamos Canyon.  October 2001 image of south-facing slope just above Los Alamos Reservoir.  

## Slide 15

**Notes:**
Treated acres in North Pueblo Canyon watershed just off Pipeline Road, March 2002.  Spring greening just underway. Note treefall beginning to occur.  Density of forest’s remaining dead trees poses significant fire hazard. 

## Slide 16

**Notes:**
Regrowth of shrubs on badly burned, steep, south-facing slope in North Pueblo Canyon Watershed. Treefall has not yet begun here.  Spring greening is just starting.  Image taken March 2002. 

## Slide 17

**Notes:**
Morning mist in South Pueblo Canyon at North Road.  Note V-shaped, pipe “trash rack” installed in creekbed, which is muddy from recent flashflood. Burned logs and debris are in foreground.  Heavy runoff in this canyon uncovered and damaged a sewer main downstream, affecting service to the north half of Los Alamos.  August 2001.
