I've done this scene many times, but never quite right. Anyways, here's a fun sketch that I liked enough, and felt fit well. (Wherein Legolas gets Gandalf back for his crabby remark!)
`If Gandalf would go before us with a bright flame, he might melt a path for you,' said Legolas. The storm had troubled him little, and he alone of the Company remained still light of heart.
`If Elves could fly over mountains, they might fetch the Sun to save us,' answered Gandalf. `But I must have something to work on. I cannot burn snow.' ........
Aragorn was the tallest of the Company, but Boromir, little less in height, was broader and heavier in build. He led the way, and Aragorn followed him. Slowly they moved off, and were soon toiling heavily. In places the snow was breast-high, and often Boromir seemed to be swimming or burrowing with his great arms rather than walking.
Legolas watched them for a while with a smile upon his lips, and then he turned to the others. `The strongest must seek a way, say you? But I say: let a ploughman plough, but choose an otter for swimming, and for running light over grass and leaf or over snow-an Elf.' With that he sprang forth nimbly, and then Frodo noticed as if for the first time, though he had long known it, that the Elf had no boots, but wore only light shoes, as he always did, and his feet made little imprint in the snow.
'Farewell!' he said to Gandalf. 'I go to find the Sun!' Then swift as a runner over firm sand he shot away, and quickly overtaking the toiling men, with a wave of his hand he passed them, and sped into the distance, and vanished round the rocky turn.”
