An advanced deposition technique known as glancing angle deposition was used to fabricate randomly seeded magnetic cobalt columnar nanostructures. The existence of nanocolumns was confirmed by the cross-section scanning electron microscopy. The evolution in the magnetization reversal mechanism as a function of the film thickness was investigated. The coercivity H_{C} and M_{R}/M_{S} ratio (where M_{R} and M_{S} denote the remanent and saturation magnetization, respectively), derived from the magnetic hysteresis loops, are discussed as a function of the angle between the external magnetic field and the surface normal. The direction of the magnetization easy/hard axis and the columns inclination angle were determined on the basis of the angular dependences of the H_{C} and the M_{R}/M_{S}. A crossover from the coherent rotation, based on the Stoner-Wohlfarth model, to the curling reversal mode was observed.
