When an uplift pushes a batholith or smaller body of hardened magma toward the surface. And sometimes when magma fails to reach the surface it hardens in to rock. Over time, the forces that wear away Earth's surface such as flowing water, ice, or wind-may strip away the layers above the hardened magma and finally expose it.
Deciding if a trout is a sea trout or a brown trout can be easy if the sea trout is fresh run from the sea âsea trout are distinctively silvery in colour and may still carry sea lice. However, once they have been in fresh water for a while they return to brown trout colours.
Lake Trout are cannibalistic and you will find small trout close to the bottom in very deep water avoiding big trout in shallower water or close to the surface. The small trout above was caught in 50 feet where large trout are feeding. Note the teeth marks as this little gut got a second chance. Large trout have been known to pin bait fish against the ice using the ice like other fish use the bottom. End of season hunting is no time to finesse with small lures. This is the time to bring out the big hardware with a lot of flash, flare and rattle. Years ago, anglers would lure large fish to cut-outs in the ice with large decoys and either catch them with live bait or spear them.
