How difficult are the river and creek crossings? 

Many streams along the GDT are glacial fed which means their volume can fluctuate significantly during the day. Plan to ford hazardous river and creek crossings early in the morning when they are at the lowest level. Depending on seasonal water levels and the time of day, the following rivers and creeks can be challenging to ford: Aldridge Creek (b32), Palliser River (c4), Amiskwi River (d3), Cairnes Creek (d9), Lambe Creek (d10), Howse River (d13), Cataract Creek (e9), Maligne River (e23), Miette River (f4), Moose River (f12), Smoky River (f16), Gendarme Creek, Carcajou Creek, Chown Creek (near g2), Jackpine River (g8) and Buchanan Creek.
