The Spanish Pioneers by Charles Fletcher Lummis

The student most familiar with history finds himself constantly astounded by the journeys of the Spanish Pioneers. If they had done nothing else in the New World, their walks alone were enough to earn them fame. Such a number of similar trips over such a wilderness were never heard of elsewhere. To comprehend those rides or tramps of thousands of miles, by tiny bands or single heroes, one must be familiar with the country traversed, and know something of the times when these exploits were performed. The Spanish chroniclers of the day do not dilate upon the difficulties and dangers: it is almost a pity that they had not been vain enough to "make more" of their obstacles.

But however curt the narrative may be on these points, the obstacles were there and had to be overcome; and to this very day, after three centuries and a half have mitigated that wilderness which covered half a world, have tamed its savages, filled it with convenient stations, crossed it with plain roads, and otherwise removed ninety per cent of its terrors, such journeys as were looked upon as everyday matters by those hardy heroes would find few bold enough to undertake them. The only record at all comparable to that Spanish overrunning of the New World was the story of the California Argonauts of '49, who flocked across the great plains in the most remarkable shifting of population of which history knows; but even that was petty, so far as area, hardship, danger, and endurance went, beside the travels of the Pioneers. Thousand-mile marches through the deserts, or the still more fatal tropic forests, were too many to be even catalogued.
