I do not profess to have attained much learning in the science of geology, and speak, therefore, as one without authority. But it seemed to me on many occasions that to study the geology of the Far West, the English scientist would have to forget all he had ever learnt about physical geography and start all over again in Southern Colorado.

At first I was puzzled in the extreme to see how the mountains rose suddenly out of the great plains, without any warning almost, and without the customary foot-hills and valleys that one would expect to see clustering around a mountain range of several thousands of feet in height. Afterwards I became accustomed to this unusual formation, when I found that mountains always grow that way in the Far West, and particularly farther on in New Mexico and Arizona. All their ranges seemed like elongated "Wrekins" set in a plain of gigantic dimensions.

At Aguilar, half-way on the road to Trinidad, I met the first really Mexican town. It will be remembered that all the south-western States once belonged to Mexico and one by one they have been ceded or bought or otherwise appropriated until Mexico now is only a shadow of its former self. Nevertheless a large proportion of the population is still Mexican, in spite of the continued influx of American settlers, and consequently Mexican is spoken almost universally in addition to English as the national tongue.

Trinidad styles itself "The industrial and commercial centre of S. E. Colorado." With a population of something in the region of 14,000, it stands at the base of Fisher's Peak (10,000 feet), and it is an admirable example of the inextricable mixtures of Old Mexico and New America in the cities of the West. I took its picture and left its shining well-paved streets to track down my old friend, the Santa Fé Trail.

I got one mile away from the town and then struck. The trail climbed rapidly, skirting the Peak all the time in preparation for the Raton Pass soon to follow, which cuts right over the Rocky Mountains into New Mexico. That in itself was nothing. I am always game for a good hill-climb. But I had thought better of the Santa Fé Trail. After climbing 1,000 feet in just over a mile, it changed into the most absurd hotch-potch of ruts and mud-heaps that ever eye witnessed, and this for as far as one could see. The condition of the road strained my credulity to breaking point. Getting through the far-off mud-hole at Hume in Indiana was a child's tea-party compared with this. In half an hour I did just 100 yards and then, after resolutely determining to return to Trinidad and take the train, I found that to go back was as much out of the question as to go forward. It simply couldn't be done single-handed. To turn Lizzie round would require nothing less than a sky-hook and pulley-blocks.

I left her standing in a huge rut in the middle of the road and reconnoitred to see how far this appalling state of affairs continued.

Fortunately a Flivver appeared round a bend in the road ahead, coming in the opposite direction. It heaved and swayed and bumped and side-slipped and hiccoughed its way along. I watched it until it finally reached the spot where Lizzie blocked the way. Then something had to be done. The car had two occupants, both hefty-looking men, whom I enlisted to my aid. Together we lifted and pulled and heaved and pushed until the worst was past, and then I struggled on alone.

Farther into the mountains we travelled; higher and higher we climbed. In places the trail was hewn out of the rugged mountain sides, and except in a few places there was hardly room for more than one vehicle to pass. Occasionally a "washout" would be encountered where a mountain stream had encroached on the road and washed it away altogether. Then would come a short detour over a gap in the bank, with the grassy slope strewn with branches and small tree-trunks to prevent the unfortunate vehicle sinking in and thus permanently blocking all progress that way.

The ascent of the Raton Mountains by the Raton Pass is made amongst some of the most beautiful scenery imaginable. The trail is only visible a few yards ahead and is lost in sudden twists and turns as gradually the mountain slopes are devoured. On the right, almost behind, are still to be seen the famous Spanish Peaks towering like twins in solitude above the rest of the Sangre de Cristo range, some forty miles away. Soon we shall be leaving Colorado State behind us—Colorado the Glorious, the Beautiful, the Great.

It is said that "amongst all the mountain kingdoms, Colorado seems to stand easily first in physical adornment: not even Switzerland and her Alps offering more than a fair comparison." Mont Blanc, the highest peak in the Alps, is 15,784 feet high, while Colorado has many peaks lacking little of this height. The lowest depths of some of Colorado's famous parks are higher than the average height of the Alpine Chain.
