Drawing that shows the cross section of a trail entitled 'Geotextile Placement'. This gives an illustration for how to build a trail using geotextile to separate the ground from the mineral soil used for the trail. The following are labels and descriptions for each:

• There are two side ditches, each on one side of the trail, that are labeled 'Side ditch'. Each is labeled with a slope of 1:1 and is 300 mm (12 in) deep.
  
  
• The 'Ground line' is labeled and shown with a dashed line.
  
  
• A layer of 'Geotextile' is labeled with an arrow showing its location. The 'Mineral soil' above it and the 'Underlying boggy soil' below it are also labeled.
  
  
• The mineral soil has a width between the two log retainers labeled as '1 m (3 ft)', and arrows are used to show this area. The mineral soil also has a crown above the log retainers which is labeled 'Minimum crown 50 mm (2 in)' and is shown with arrows.
  
  
• There are wooden stakes on the outsides of both log retainers which are labeled with an arrow and the text 'Wooden stakes'.
  
  
• The two logs are labeled with an arrow and the text 'Log retainers 150 to 200 mm (6 to 8 in)'.
  
  
• Another smaller in the upper right shows that a rock can also be used for the retainer. This is labed with the text 'Rock retainer option'.
